Description

We study quasi-particle excitations in N=4 non-commutative U(1) Yang-Mills theory at finite temperature. Above some critical temperature there is a tachyon in the spectrum of excitations. It is a collective transverse photon mode polarized in the non-commutative plane. Thus the theory seems to undergo a phase transition at high temperature. quasi-particles generically exceeds the speed of light at low momentum.
