Research Description:

One of the primary thrusts of the theoretical high energy group at the University of Oklahoma lies in developing nonperturbative methods for use in quantum field theories and gauge theories. Previous programs under development included the quantum finite-element lattice method, variational perturbation theory, the delta expansion applied to symmetry breaking, and analytic perturbation theory. Substantial efforts had been made to understand the possible existence of magnetic monopoles. A new class of quantum field theories which respect PT symmetry but not Hermiticity has been thoroughly investigated. Applications are being made to quantum electrodynamics and quantum chromodynamics. Vacuum energy phenomena (the Casimir effect) are being studied in contexts ranging from cosmological through hadronic to condensed matter systems. Particularly of interest are questions of divergences encountered in such calculations, and of thermal corrections and other effects in real materials. Gravitational implications of quantum vacuum energy are particularly important. Techniques for extracting exact Casimir interactions between distinct bodies are being developed. Repulsive Casimir forces, and related negative entropy phenomena are being investigated, and applications to practical devices are under study.
