Center for Theoretical Studies of Physical Systems The Center for Theoretical Studies of Physical Systems was established under the NSF CREST program, although the Center has received funding from other federal and state agencies, and the private sector. Research at the CTSPS is carried out through a dynamic clustering of researchers in the areas of atomic and molecular physics, mathematical physics/applied mathematics, signal and image processing, complex systems, and molecular dynamics and materials. National and international collaborations by the Center have led to pioneering research in the understanding of small angle electron scattering by atoms and molecules (impacting advanced laser systems, rocket propulsion, plasma fusion, etc.). The mathematical physics group has developed new computational theories that significantly clarify the role of wavelet analysis in physics. New theoretical breakthroughs in the application of inverse scattering techniques promise to positively impact the development of quantum scale cascade lasers, leading to a more efficient infrared sensor technology. Research in the design of new materials and their electronic structure is making important contributions in the field of material science. CTSPS researchers in complex systems, i.e., self-organizing systems, are part of an international group studying large crowd movements, such as pedestrian and vehicular traffic, based on forming ‘psychological models’ of individual behavior. One of the strongest partnerships of the Center involves the Army Research Laboratory Advanced Sensors Federated Laboratory Consortium, in which major research institutions, including MIT, Stanford, Michigan, Maryland, and Georgia Tech, participate, as well as the industrial partners of Lockheed Martin and ERIM. Recent research projects by the Center include the following: Boundary Controllability of Fluid/Structure Hybrid Systems Design of Semiconductor Heterostructures by Inverse Scattering Techniques Density Functional Reactivity Indices Dispersion Relations in Atomic Physics Electron Excitation of Atoms, Molecules, and Ions at Small Scattering Angles Electronic Structure of Metallic Clusters Energy Levels, Oscillator Strengths, and Integral Cross Sections of S(V), Fe(XVII), Ar, Kr, Xe, and Neon-like Titanium Glassy Surfaces of Metallic Nanocrystals Modeling/Analysis of a Laminated Beam with Embedded Piezoceramic Patches Modeling, Design, and Control in Smart Material Systems Modeling of Rubber Elasticity Moment Wavelet Quantization Photoionization of Atomic and Ionic States Regge Poles Calculations for Singular Potentials
