Lattice Gauge Theories

SU(n) gauge theories at finite temperature are examined in terms of the spontaneous breaking of a Z(n) symmetry. It is suggested that the phase transition at finite temperature results from the formation of "bubbles" of an alternate Z(n) vacuum. These Z(n) bubbles are analyzed for lattice gauge theories in the dilute gas approximation and the results are compared with the Monte-Carlo calculations of McLerran and Svetitsky.

Green's Function Monte Carlo

The momentum distribution and condensate fraction of liquid and solid 4He determined from Green's function Monte Carlo calculations using the HFDHE2 pair potential are described. The one-body density matrix and the momentum distribution for liquid 3He derived from variational and fixed-node Green's function Monte Carlo calculations are also reported.
