Deconfinement transition at weak coupling in Yang-Mills theory on a torus
Thomas Schaefer
We describe a weak coupling realization of the deconfinement transition in gauge theory compactified on . We consider Yang-Mills theory with a single Weyl fermion of…
Instantons and Monte Carlo Methods in Quantum Mechanics
Thomas Schaefer
In these lectures we describe the use of Monte Carlo simulations in understanding the role of tunneling events, instantons, in a quantum mechanical toy model. We study, in particul…
QCD and the eta prime Mass: Instantons or Confinement?
Thomas Schaefer
We argue that lattice calculations of the mass in QCD with colors performed at non-zero baryon chemical potential can be used to study the mechanism responsible for th…
Possible Color Octet Quark-Anti-Quark Condensate in the Instanton Model
Thomas Schaefer
Inspired by a recent proposal for a Higgs description of QCD we study the possible formation of a color-octet/flavor-octet quark-anti-quark condensate in the instanton liquid model…
Comment on "On the Origin of the OZI Rule in QCD", by N. Isgur and H. B. Thacker
T. Schaefer, E. Shuryak
We comment on the recent paper (hep-lat/0005006) by Isgur and Thacker on the origin of the OZI rule in QCD. We show that instantons explain the sign and magnitude of the observed O…
