The members of the Physics and Chemistry of Materials Group in the Theoretical Division seek to understand how basic forces operating at the atomic level manifest themselves in the properties of matter at the macroscopic level. The group maintains theory, modeling and simulation capabilities in a broad set of materials-related areas. Current activities in the group include research in atoms, molecules, solids, liquids, gases, and plasmas. Group projects include the development and application of theory and techniques for calculating the electronic properties of molecules, solids, and liquids, atomistic simulations of materials, the dynamics and kinetics of chemical reactions; equation of state and thermodynamics; mechanical properties; reactive burn and flow, atomic structure and collision theory, catalysis, opacities, and the physics of hot and warm dense matter. Particular applications of this research include the properties of simple metals, transition metals, and actinide elements, molecules, alloys, and compounds; radiative properties of hot dense matter; the properties of polymers, organics, and energetic materials, and theory and technologies for energy security.

Conducts basic and applied research in theoretical continuum dynamics, modern hydrodynamic theory, materials modeling, global climate modeling, numerical algorithm development, and large-scale computational simulations. There is an emphasis on developing advanced numerical methods for continuum dynamics at all flow velocities and strain rates, and coupling these methods to constitutive models for solid material response and other physical processes such as turbulence, chemical reactions, combustion, phase change, heat and mass transfer, and plasma behavior. The Fluid Dynamics Group’s portfolio of research activities represents fundamental science conducted in support of nuclear weapons design, performance, and safety; nuclear reactor design and fuel performance; conventional weapons design and performance; global climate modeling; internal combustion engine design and performance; process chemistry for the oil and chemical industries; and casting and materials fabrication.

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.
