| | Applied Physics and Mathematics |
 | | In theoretical plasma physics, research is conducted in the fluid theory of plasma equilibrium and stability, active control of MHD instabilities, the kinetic theory of transport, and the development of techniques based on the theory of general coordinates and dynamical systems. |
 | | Solid-State Physics: Research in solid-state physics covers nanoscience and nanoparticles, the optical spectroscopy of semiconductor structures that are subjected to high pressure, electric transport and inelastic light scattering in low-dimensional correlated electron systems, fractional quantum Hall effect, heterostructure physics and applications, molecular beam epitaxy, grain boundaries and interfaces, nucleation in thin films, and surface physics. |
 | | Applied Mathematics: Current research encompasses analytical and numerical analysis of partial differential equations, large-scale scientific computation, fluid dynamics, multiscale phenomena and homogenization, dynamical systems and chaos, as well as applications to various fields of physics and biology. |
