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.

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.
