Oxide transistors have advanced significantly, gradually replacing materials like amorphous silicon in certain applications due to their excellent performance, transparency, and flexibility. These qualities make them crucial for displays, sensors, and other flexible electronics. However, challenges remain, particularly in the development of p-type oxide semiconductors, which are much less advanced than n-type ones. P-type semiconductors with high hole mobility, stability, and easy fabrication are scarce, hindering the progress of complementary oxide technology. Additionally, the rapid evolution of display technology has raised the bar for oxide transistor driving technology, making it increasingly difficult to balance mobility and stability. Achieving this balance requires in-depth research and innovative solutions. Oxide transistors also show promise for use in storage devices, logic circuits, and 3D integrated systems. With ongoing research, oxide transistors have the potential to transform industries by enabling more efficient, durable, and versatile electronic and optoelectronic devices.

Originating from the discovery of the quantum Hall effect in the 1980s, the study of topological phases of matter have received sustained attention in the past few decades. Due to its universal nature, this field has expanded into new and exciting areas, particularly ultracold atomic gases and optics.

 

The implementation of topological states and their physical parameters in these new areas differ significantly from those in electronic materials explored in the pioneer studies. For instance, the extreme dilution and ultralow temperatures of atomic gases result in much longer timescales for dynamical processes, offering unique experimental opportunities. Current techniques allow researchers to monitor non-equilibrium processes driven by coherent quantum dynamics with exceptionally high temporal resolution and perform rapid parameter switches (quenches) to initiate various dynamical processes. These experimental advantages provide powerful platforms to explore topological dynamics in ultracold atomic gases and optical systems, including topological phase transitions, Floquet topological phases, quantized transport, and nonlinear phenomena. Moreover, these settings enable the creation and study of diverse topological states, such as vortices, vortex solitons, hopfions, skyrmions, and topological insulators, offering insights into their fundamental properties and potential applications.

 

We expect this special issue will provide a comprehensive overview of the latest achievements and advancements in this field, offering readers high-quality research contributions. We warmly invite theoretical and experimental research groups, as well as individual authors, to submit original research articles and reviews to the special issue. While there are no strict length restrictions for articles, reviews should have a minimum length of 15 pages. Publication fees will be waived for all contributors, and all articles published online will be freely available for download. The submission deadline is October 31, 2025. Authors who require an extension are kindly requested to inform us in advance.

 

We look forward to receiving your submission.

The modern paradigm of functional new materials involves engineering structural units with specific functions to control their macroscopic performance, a concept that applies across a wide range of material science disciplines, from dynamic wave manipulation to low-dimensional quantum systems. These functional units overcome the elemental limitations of natural materials, thereby broadening the potential for designing and developing new materials with groundbreaking and transformative properties. For instance, the concept of metamaterials, initially developed for electromagnetics, has since found wide-ranging applications in controlling the propagation of dynamic waves, including acoustic waves in fluids, elastic waves in solids, and surface water waves. Over the past decade, research in this field has made significant strides, evolving from the study of negative-index metamaterials and transformation optics to the exploration of cutting-edge topics like novel wave manipulation using metasurfaces and topological materials. This special topic aims to further advance the field of functional metamaterials by exploring new theoretical concepts, innovative design strategies, cutting-edge experimental implementations, and novel devices and applications.

Spatial and time assembly, which refers to the deliberate arrangement of functional units in space and time following specific rules and patterns, is crucial for determining the physical properties of functional materials. This approach, particularly the ability to manipulate various ordered arrangements — such as lattice symmetry, spatial or temporal gradients, and disordered designs — provides a versatile toolkit for modulating coupling and enhancement effects. These effects, in turn, enable the discovery of extraordinary properties or entirely new behaviors that surpass the individual characteristics of the constituent functional units. In the realm of classical wave systems, spatial and time assembly is playing an increasingly important role in pushing forward both theoretical and experimental developments in advanced physics fields, such as non-Hermitian physics, topological phenomena, and space-time wave dynamics. It offers a means to observe complex wave phenomena and novel wave-matter interactions. This special topic aims to highlight recent breakthroughs in these fields, particularly with respect to their practical applications. The special topic will explore new theoretical frameworks, innovative structural architectures, experimental observations, device fabrication techniques, and system applications that contribute to advancing our understanding of wave interactions within metamaterials, especially those with specific spatial and time assembly designs.

Ultrafast electron microscopy (UEM) combines modern electron microscopy with pump-probe technique, which enables ultrafast imaging, diffraction and electron-spectroscopy with nanometer-femtosecond spatiotemporal resolution.  The unique advantages of UEM enable powerful capabilities in the study of dynamic phenomena in materials, nano-systems and biology. In the last decades, the application of UEM in the research of non-equilibrium state including structural dynamics, magnetic dynamics, and other light-matter interaction phenomena brings new vision to the nature of multi-body interaction in materials and nano-systems. In addition, UEM has exhibited great application in the field of nano-photonics and electron optics based on the photon-induced near field microscopy (PINEM) effect, a phenomenon of quantum interaction between free electrons and optical field mediated by medium. The imaging of surface plasma polariton, band structure measurement of optical microcavities, electron acceleration, electron pulse compression and many other fascinating researches have been realized in UEM. Furthermore, with the great progresses in generation of attosecond optical pulses in the past decade (awarded the Nobel Prize in Physics in 2023), several strategies for achieving attosecond electron microscopy have been proposed and some of them have even been successfully demonstrated recently, providing an unprecedented powerful tool for study light-matter interactions on the nanometer or sub-nanometer spatial scale within a single or few optical circles.


The development and application of UEM are still fast expanding.  The scope of this focus issue in Frontiers of Physics would cover the recent development of UEM and the novel applications in many scopes.  We do hope that the issue will form a broad overview of the current state of this cutting edge field.

Two dimensional (2D) layered materials have attracted intense research interest in both fundamental study and practical applications because of their intriguing optical and electronic properties. Thanks to the weak interlayer van der Waals force, these 2D materials can be further stacked to form artificial heterostructures without constraints from lattice mismatch. There, new degree of freedoms including components, structures and twisting angles provide unprecedented control of properties and functionalities. For example, heterostructures consisting of 2D semiconductors with strong light-matter interaction and excitonic effect have opened new door to ultrathin optoelectronics. Moreover, when two monolayers are super-imposed with carefully tuned twisting angles, a 2D moiré superlattice is formed, which has led to recent breakthrough in superconducting and correlated physics.

 

The scope of this special topic in Frontiers of Physics would cover all the aspects of experimental and theoretical studies on the optical properties and photophysical processes in 2D materials, heterostructures and Moiré Superlattices, including but not limited to:

 

 2D exciton optical properties and dynamics;

  Interfacial exciton charge/energy transfer;

  Intralayer/interlayer exciton recombination and transport;

 Spin and valley relaxation and manipulation;

 Nonlinear optics and modulation;

 Moiré modulated optical properties and exciton dynamics;

  Correlated electronic states and hybrid exciton.

As Moore's Law approaches the physical limit, the traditional von Neumann architecture is facing challenges, among them, one of the most promising device candidates is memristor. In recent decades, memristors have developed rapidly due to their simple sandwich structure, good compatibility and availability with existing CMOS processes. Recently reported memristors show attractive features, such as high ON/OFF ratio, low power consumption, fast switching speed and high durability, which can respond to the needs of emerging applications. These characteristics of the memristor are produced by applying an external bias voltage to change the resistance state. By exploiting complex material types and a variety of resistive mechanisms, the research on memristors and their potential applications has become the frontier and hotspot in physics, electronics, materials, nano and other fields, and has shown the characteristics of interdisciplinary integration. In the field of basic research and practical application of memristors, their complex material types and various resistance mechanisms play a crucial role in device performance and application prospects. The material types and resistance variation mechanism of memristors have laid a solid foundation for predicting and improving device performance and expanding application prospects. Whether it is a non-volatile memristor or a volatile memristor, the material type and resistance variation mechanism are extremely important in influencing the application prospects of information storage, neural networks and logic operations. In particular, to address power and energy efficiency problems in neuromorphic computing, memristors are strong candidates. These endow memristors with the potential to trigger a circuit revolution, which may once again extend the life of Moore's Law, open up new directions for research in the field of information storage and information processing, and its industrialized application may also bring about a new round of technological revolution.

 

The scope of this focus issue in Frontiers of Physics would cover the aspects on the materials, mechanisms and applications of memristors from experimental synthesis, characterizations, theoretical calculations, etc. Articles reporting on the latest progress in the controllable growth of new materials, switching mechanism, application prospect of memristors and the exploitation of them towards innovative and practical devices are expected. Research works addressing approaches to switching mechanism and application prospect of memristors from both experimental and theoretical points of view are also welcome.

The mystery of chirality is a critical problem in nuclear physics, and it also shares common interests in many other fields including chemistry, biology, molecular physics, etc. It has been 25 years since the first proposal of chirality in nuclear systems in 1997 by Stefan Frauendorf and Jie Meng. Since then, tremendous efforts and achievements have been made from both experimental and theoretical sides. Experimentally, more than 50 candidate chiral doublet bands have been proposed in a number of odd-odd, odd-mass, and even-even nuclei in the mass regions of 80, 100, 130, and 190. Theoretically, various approaches, ranging from phenomenological models to microscopic theories, from geometric to algebraic models, from mean-field models to beyond mean-field models, have been developed. Moreover, the concept of multiple chirality proposed in 2006 had significantly deepen our understanding of chiral nuclei. In particular, it brings many interesting topics and phenomena, for instance, the simultaneous breaking of chiral and other symmetries, the new observables and fingerprints, as well as the boundaries of chiral nuclei. Obviously, although 25 years have passed, the study of nuclear chirality is still one of the most active fields in nuclear physics.  

The scope of this topical collection in Frontiers of Physics will be devoted to the 25th anniversary of nuclear chirality. Both theoretical and experimental papers are welcome. 

We are looking for high profile scientists to contribute Review, Topical Review, View & Perspective, or Research Article. There is no strict length limit for each article, and for each review at least 15 pages length is highly expected.

The isolation of graphene in 2004, rapidly followed by the discovery of its amazing properties, has generated an intense research effort on two-dimensional (2D) materials in the past decade. In 2D materials, the atoms forming the compound are arranged into planes (layers) that are held together by strong in-plane bonds, usually covalent. To form a 3D crystal, the atomic layers are stacked in the out-of plane direction with weak van der Waals interactions. This allows the exfoliation of bulk crystals and the fabrication of thinner flakes, even down to the single layer limit. Such a unique structural feature of 2D materials endows them with various unconventional optoelectronic properties as compared to their bulk, zero-dimensional (0D) and one-dimensional (1D) counterparts. Due to the atomically thin layered structure, 2D materials are likely to have the greatest impact on geometric scaling for dimension downscaling in modern electronics and optoelectronics. For example, the high carrier mobility, tunable polarity of carriers, high light-absorption efficiency, and tunable bandgaps enable 2D materials suitable for next-generation transistors, memories, diodes, photodetectors, photovoltaics, and so on. Furthermore, the strong light-matter interaction and excitons with long lifetime provides unparalleled control over device
properties and possibly new physical phenomena. The challenges in exploring the optoelectronic properties of 2D materials will be addressed in this special topic. Finally, a variety of potential applications based on these 2D materials will also be reviewed.

The scope of this focus issue in Frontiers of Physics would cover all of the aspects from experimental synthesis, experimental characterizations, electronic properties, optical properties, etc. This special topic will present the major recent progress in this field from the best experimental and theoretical teams all over the world. We do hope that it will form a broad overview of the current state of this cutting edge field.

As a typical post-graphene 2D material, MXene has attracted tremendous attention since 2011.  MXenes are a class of two-dimensional inorganic compound, comprising of a few-atoms-thick layer of transition metal carbides, nitrides or carbonitrides. MXenes combine metallic conductivity of transition metal carbides and hydrophilic properties that occur as a result of their hydroxyl or oxygen terminated surfaces. Given the material properties of MXenes, there are numerous promising applications that are beginning to be realized, which include supercapacitors, lithium and sodium-ion batteries, composite materials, sensors, and optoelectronic/photonic devices. 
 
In view of these developments, we, together with the editorial office of the journal "Frontiers of Physics", have decided that it is timely to edit a special topic of this journal, dedicated to the topic of "MXene and Its Applications". The special topic will mainly feature review and topical review articles that could provide a comprehensive overview of both the current status of the field and the future direction of it as well as several important original research papers, providing an overview of the research and development in the field.
 
We are looking for high profile scientists from China and overseas to contribute Review or Topical Review in the foresaid areas. Please feel free to choose the title and adjust the content that best fits the special topic. Co-authorship is welcome. There is no strict length limit for each article, and for each review at least 15 pages length is highly expected.
 
The sample article (TEX template) can be downloaded via http://journal.hep.com.cn/fop/EN/column/column15258.shtml and the new manuscript can be submitted online through http://mc.manuscriptcentral.com/fop. All PDFs of the special topic will be open accessed, and a copy of the volume will be mailed to all participants.
