In studying the dynamics of large N_c, SU(N_c) gauge theory at finite temperature with fundamental quark flavours in the quenched approximation, we observe a first order phase transition. 0000041695 00000 n
Depending on the rates of the dynamical processes the wetting transition is either of first or second order. 0000051654 00000 n

More recently there is increasing evidence that in many systems which are close to a quantum critical point (QCP) different phases are in competition. Finally, we discuss the universal behavior of systems with a weak first-order zero temperature transition in particular as the transition point is approached from finite temperatures. These could allow for the generation of the matter-antimatter asymmetry or potentially observable gravitational waves. A quark condensate forms at finite quark mass, and the value 0000007802 00000 n

The phase transition we just described involves a change of colour of parts of the ﬁgure, and colour is a scalar variable, so we expect we will need scalar modes. 0000041607 00000 n
