T-6 staff are involved in a broad range of issues in astrophysics. These include (1) stars from cradle to grave - star formation, stellar evolution, stellar oscillations, supernovae, nucleosynthesis, chemical evolution; (2) relativistic astrophysics involving white dwarfs, neutron stars, and black holes; and (3) large scale structure in the universe, cosmic magnetic fields, and cosmology. There is some ongoing research on planet formation, impacts by comets and asteroids in the solar system, and high energy density plasmas.

T-8 conducts research in field theory, particle physics, and gravity, including applications to astrophysics and cosmology. The group's efforts encompass (i) a study of strong interactions of hadrons using lattice quantum chromodynamics to calculate the hadron spectrum, quark masses, and weak matrix elements, especially those that are required to quantitatively understand the experimentally observed CP violation; (ii) properties of neutrinos and their applications to problems in astrophysics and cosmology; (iii) gravity and cosmology to explain the cosmic microwave background radiation and large scale structure of the universe; (iv) large-distance tests of gravity; (v) and a significant effort to elucidate the structure of theories beyond the standard model which invoke supersymmetry and extra dimensions to explain electroweak symmetry breaking and the origin of masses of elementary particles. Fundamental issues of quantum field theory forms another key focus of T-8 research, especially in the arena of systems far away from equilibrium, to understand the early universe and the quark gluon plasma created in relativistic heavy ion collisions.

T-11 is active in many aspects of condensed matter theory including electronic and structural properties of metals, semiconductors, compounds and alloys, polymers, microscopic modeling of materials properties and textures, fundamental studies of nonlinear and nonequilibrium systems, and investigations of the properties of heavy fermions, high temperature superconductors, organic charge-transfer salts, and other strongly correlated electronic systems. Ongoing work involves the development of advanced algorithms for scientific computing, e.g., quantum Monte Carlo, molecular and Langevin dynamics involving multiple time and length scales, and the development of visualization tools for large data sets.

T-12 is staffed by theoretical chemists and physicists who work on projects aimed toward an improved understanding of the behavior of materials. Projects in the group seek to describe how basic forces operating at the atomic and molecular level manifest themselves in the properties of matter at more macroscopic levels. Current activities in T-12 include research both in gas phase and condensed phase phenomena, and projects apply state-of-the-art computational approaches in fundamental and applied studies of the physics and chemistry of molecules and materials.

T-13 creates new methods for solving complex problems and applies them to problems at the forefront of technology. Computational fluid modeling, simulations of large quantum computers, design of solid state quantum computers, granular flows, and nanotechnology are of great interest to researchers in this group. Current research includes modeling of the spread of influenza, determining the shapes of functionally equivalent biological molecules, rapid and accurate modeling of enhanced oil recovery processes, fundamental turbulence modeling, designing laser-matter interaction systems for the National Ignition Facility, determining the predictability of large complex systems, and creating new information scanning and gathering systems.

T-15 studies the theory of the fourth state of matter, plasma, or ionized gas, after solid, liquid, and gas. A major activity is computer modeling and simulation of plasmas, developing and applying such widely-used codes as the NIMROD 3D, nonlinear time-dependent simulation code for magnetically confined plasmas; and the DCON code for rapid determination of the stability of axisymmetric toroidal plasmas. Numerical simulation of magnetized plasmas is particularly challenging because of the high degree of anisotropy and range of length and time scales. T-15 specializes in development of novel numerical methods to deal with this challenge.

The Center for Nonlinear Studies identifies and studies fundamental nonlinear problems and promotes the use of the results in applied research. It stimulates interdisciplinary research and information exchanges inside and outside the Laboratory, and provides a Laboratory focal point for collaboration with academic and other centers of excellence in nonlinear science. CNLS disseminates recent developments in nonlinear science and introduces student and postdoctoral researchers to this subject. CNLS achieves these goals by hosting conferences and workshops, through an extensive visitor, postdoctoral and student program, and through interactions with Laboratory staff. The major research areas include biological physics, statistical physics and nonequlibrium statistical mechanics, turbulence, geophysics, and condensed matter physics.
