|---|
The State Key Laboratory of Magnetic Resonance and Atomic and Molecular Physics (MRAMP), supported by Wuhan Institute of Physics and Mathematics of the Chinese Academy of Sciences (CAS), was established in 1986 and opened to the public in 1988. It is one of the first batches of 18 public laboratories of CAS.
The main research interests of MRAMP are focused on the atomic and molecular structure and dynamics and their environmental effects by the resonance interactions of electromagnetic waves (from radio to optical frequencies). These include the following: methodology and application of magnetic resonance imaging (MRI) and spectroscopy (MRS) in the life sciences; high-resolution nuclear magnetic resonance (NMR) and its application in the study of biomolecular structure, molecular interaction, and dynamics; high-resolution solid-state NMR and its application; cold atoms physics; quantum information and quantum manipulation; laser trapping of single atoms and ions; precision measurements; atomic structure and characteristics in strong external fields; laser spectroscopy and its applications; and high-performance atomic frequency standards.
Training specialists and recruiting talents have always been the main subject of MRAMP. Over past 5 years, 6 professors have been awarded by the National Distinguished Young Scholar Funding, 11 staffs have been recruited by the Program of Overseas Outstanding Scholars, and 3 professors have been appointed as chief scientists of the National 973 Projects. Now, MRAMP has 36 fixed staffs. Among them are 25 professors and 1 academician of CAS.
After the development for over 20 years, MRAMP has become an irreplaceable research force in the field of NMR and atomic and molecular physics. It has obtained 29 national and provincial awards for natural science and technological progress. At present, MRAMP is undertaking a number of national projects, such as the 973 Projects, and the key projects of the NSFC and CAS. Since 2005, 474 papers have been published by MRAMP and have been cited 1670 times. Among them, 29.5% appeared in JCR top 15 journals, with 1 paper in Science, 3 in PNAS, 12 in PRL, and 7 in JACS.
MRAMP has achieved a series of important progress recently. This includes the approach for understanding the dynamic basis of host–microbiome symbiosis, which provides a foundation for the development of functional metagenomics as a probe of systemic effects of drugs and diet that are of relevance to personal and public health-care solutions (PNAS2008, 105: 2117; PNAS 2008, 105: 6127), and accurately probing slow motions on millisecond timescales with a robust NMR relaxation experiment (JACS 2008, 130: 2432), and that the modulation of ligand-binding affinity through concerted interdomain structural and dynamic rearrangements may represent a general property of multidomain scaffold proteins (JACS 2009, 131: 787).
In the field of atomic and molecular physics, the matter-wave self-imaging resulting from atomic center-of-mass motion-based interference was demonstrated (PRL 2008, 101: 250401); with a semiclassical model, the distinct roles of nuclear Coulomb attraction, the final-state electron repulsion, and the electron-field interaction in the correlated electron emission for helium double ionization in intense laser field were identified (PRL 2008, 101, 233003); preliminary measurement and 450-second locking of the optical transition in a single trapped calcium ion were successful; the linewidth of a trapped Hg ion microwave frequency standard was narrowed to the order of Hz; compact rubidium atomic clock was industrialized. In addition, a single neutral rubidium atom was successfully trapped in an optical dipole trap recently, which will greatly enhance the ability for quantum simulation and quantum manipulation using atoms.
Undoubtedly, MRAMP will continually contribute to the scientific progress in both magnetic resonance and atomic and molecular physics.
