Introduction
Research of atomic and molecular physics under extreme conditions is an important direction of physics study in 21st century，which are of great scientific significance but also can push forward the national strategic high technology and the related interdisciplinary research. Our group focus on the research of cold atomic physics, ultraclold neutral plasma and the interaction of matter with a strong laser field. Such investigation are not only a fundamental problem of atomic and molecular physics, plasma physics and condensed matter physics and quantum information sciences, , but also have comprehensive applications in inertial-confinement fusion ,and new energy weapon physics, etc.
Introduction
Founded in 2003, the Laboratory for Biomechanics of Animal Locomotion (BALL) addresses itself to the research on biomechanics and bionics of the flying and swimming animals, such as insects, bats, fish and dolphins. The interaction between the animal’s flexible physical bodies and the surrounding fluid (air or water) can generate the forces which are needed in its locomotion. The high performance of animal locomotion is magic and interesting, with that more and more researchers and students fall in study. The subjects involve not only the fluid dynamics, but also the motor nerve, muscle mechanics, structure dynamics, mechanical constitutive relations of biomaterials et al.
The research on fish swimming in this lab can be traced back to the 1980s. The group, led by Professor TONG Bing-Gang, developed the three-dimensional waving plate theory to investigate the swimming performance of fish undulatory motion. The three-dimensional effects, considered firstly following Lighthill’s classical elongated body theory and T.Y. Wu’s 2D waving plate, can be reduced by the undulatory motion. This work was cited around the world, and it has been reviewed in Triantafyllou’s paper (Annual Review of Fluid Mechanics, 2000).
By the turn of the century, Professor TONG organized an effective research team in the biomechanics, including his group and the big mechanical engineering group in the University of Science and Technology of China (USTC). In this team, the materials and methods, including in vivo visualization of experiments, model experiments, numerical simulation and theoretical modeling, has been developed systematicly. The interactional exchange is frequent day by day.
In 2003, the Laboratory for Biomechanics of Animal Locomotion was founded in the Graduate School of Chinese Academy of Sciences. In the same year, the team prepared and organized the 214th XiangShan-Science Conference – “Biomechanics and Bionics of flying and swimming animals”. Prof. TONG’s principal speech, as one of the two keynote speeches, and the other 5 special reports from this team were the part of total 19 reports in this conference. The team has been supported by 2 and 2 long-term funded projects from the National Science Funding of China (NSFC) and Chinese Academy of Sciences (CAS) respectively.
In the recent paper(Ann. Rev. Fluid Mech., 2011), T.Y. Wu’s reviewed the 7 papers, published by Prof. TONG and his PH.D students. in which the paper on theoretical modeling has been regarded as one of four representative articles for insect flapping flight under large angles of attack. He also has mentioned their in-house numerical platform two times, which coupled the deformable body dynamics and the fluid dynamics and successfully used in the study of free fish swimming.
The laboratory now is equipped with a set of high performance parallel computing cluster (160 CPU) and a circulating water channel, which can help the lab members to work on theoretical modeling, numerical studies and small experiments.
Welcome to the laboratory for biomechanics of animal locomotion.

Introduction
Theoretical condensed matter physics and computational materials physics [T(CMP)2] laboratory at University of Chinese Academy of Sciences (UCAS) is primarily devoted to studying theoretically the basic issues involved in condensed matter physics and materials science.
Condensed matter physics is the science that deals with the structures, properties and fundamental laws of condensed matter. It is connecting atomic-scale physics to the properties of macroscopic systems or everyday things. The essence of the subject can be revealed in ten words: "The whole is more than the sum of its parts."The emergent phenomena are its main themes of exploration.
By invoking experimental, theoretical and computational methods, people push forward the advances of condensed matter physics through expected and unexpected discoveries, understanding exotic phenomena as well as properties of new materials, and so forth. Thus, condensed matter physics and materials physics are the twin subjects in physics.
Our research fields involve with quantum magnetism, molecular magnetism, strongly correlated systems, superconductivity, superfluidity, spintronics, computational materials physics and chemistry, mesoscopic physics, statistical physics, nanoscience, clean energy, etc.
The modern analytical and numerical methods in condensed matter physics are applied or proposed in our research, including bosonization, fermionization, conformal field theory, non-equilibrium Green function, various mean-field, quantum Monte Carlo, density-matrix renormalization group and variants, linearized tensor network renormalization group, DFT calculations, etc. The computing facility with PC clusters of 320 nodes is available, and the supercomputing resources in CAS can also be used.
