Instability of Non-Commutative SYM Theories at Finite Temperature

  title={Instability of Non-Commutative SYM Theories at Finite Temperature},
  author={Karl Landsteiner},
We extend our previous work on the quasi-particle excitations in N = 4 non-commutative U(1) Yang-Mills theory at finite temperature. We show that 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. Furthermore we find that the group velocity of quasi-particles generically exceeds the speed of light at low… CONTINUE READING
