My specialty is theoretical high energy physics.

Most of my research, over the years, has focused on non-perturbative aspects of QCD, particularly the quark confinement problem. This has always been my main concentration.

But I have also dabbled, from time to time, in quantum gravity, inflationary cosmology, and condensed matter physics.

Right now I am working on:
the precise distinction between the Higgs and confinement phases of a gauge Higgs theory, when these regions of the phase diagram are not entirely separated by a line of thermodynamic transition. This ties in with the meaning of the word "confinement," when (as in QCD) the static quark potential flattens out at large quark-antiquark separations.

the possibility that the gauge and Higgs fields surrounding a static fermion have a spectrum of localized excitations. These excitations would appear as heavier versions of the lighter particles.

an improved Hartree-Fock treatment of the two-dimensional Hubbard model with possible applications to cuprate superconductivity.

Research Opportunities for graduate students
I am looking for a few good students to participate in my research effort in lattice gauge theory. If you are an SFSU Master's degree student with
a strong interest in theoretical physics
some knowledge of computer programming
good grades in Phys 430/431 or equivalent
then you might be interested in getting involved. If so, drop by, and let's talk.
