SU(2) lattice gauge theory at nonzero chemical potential and temperature.

Description

SU(2) lattice gauge theory with four flavors of quarks is simulated at nonzero chemical potential {mu} and temperature T and the results are compared to the predictions of Effective Lagrangians. Simulations on 16{sup 4} lattices indicate that at zero T the theory experiences a second order phase transition to a diquark condensate state which is well described by mean field theory. Nonzero T and {mu} are studied on 12{sup 3} x 6 lattices. For low T, increasing {mu} takes the system through a line of second order phase transitions to a diquark condensed phase. Increasing T at high {mu}, the ... continued below

Increasing T at high {mu}, the system passes through a line of first order transitions from the diquark phase to the quark-gluon plasma phase.
