Theoretical—Nonlinear Dynamics and Complex Networks

One of the major developments of the last two decades has been the ever-increasing interconnectivity of a broad class of information networks, including physical and data network types arising in telecommunication, social networks, and transportation and energy infrastructures. This interconnectivity has led to immense temporal and spatial complexity in modern networks and a critical need for basic mathematical theory and statistical modeling of complex interacting networks.

Theoretical—Particle and Fields

Activities in this area primarily focus on investigations on beyond the standard model applications of lattice field theory. This includes strongly coupled supersymmetric systems such as arise in hidden sector models of spontaneous supersymmetry breaking. We have also studied models of compositeness in the Higgs sector of the Standard Model, with electroweak symmetry broken by strong dynamics of a new gauge force. This has led us into developing software for the study of resonance properties from first principles, which is also useful for lattice quantum chromodynamics.

Experimental—Optical Physics

Research in optical physics covers a wide range of activities related to photons and their interaction with various materials. Experimental and theoretical research is ongoing to provide innovative solutions to today’s problems in both fundamental and application. The goals are the development of novel nanoelectronic and nanophotonic devices, creative solutions for homeland security, renewable energies, biological and biomedical investigations, solar harvesting, and smart lighting.

Theoretical—Astrophysics

Current research focuses on determining the location of dark matter in the Milky Way.  We perform n-body simulations of the tidal disruption of dwarf galaxies in the Milky Way halo, using MilkyWay@home, a 0.5 PetaFLOPS volunteer computing platform built in-house. We compare the simulations to actual Milky Way data to determine the best parameters for the simulations, thus constraining the amount and distribution of dark matter in the halo.

Physics

The Department of Physics, Applied Physics, and Astronomy prepares students to contribute to new concepts and technologies through innovative teaching methods that combine student-faculty interactions, computer-based education, and “hands-on” experience in modern laboratories.
