✦ Synopsis

We simulate two-flavour lattice QCD with at a finite chemical potential ~1 for isospin, and finite temperature. At small ,u~, we determine the position of the crossover from hadronic matter to a quark-gluon plasma as a function of ~1. At larger ~1 we observe the phase transition from the superfluid pion-condensed phase to a quark-gluon plasma, noting its change from second order to first order as ~1 is increased. We also simulate two-flavour lattice QCD at zero quark mass, using an action which includes an additional 4-fermion interaction, at temperatures close to the chirai transition on Nt = 8 lattices.

We simulate lattice QCD at a finite chemical potential ~1 for isospin (1s) at zero and finite temperatures. At some ~1 = pc QCD has a second order transition with mean-field critical exponents to a state where ( 13) is broken spontaneously by a charged pion condensate. Heating the system with PI > /
