摘要：
We study the dispersion relation for scalar excitations in supersymmetric, non-commutative theories at finite temperature. In N = 4 Yang-Mills the low momentum modes have superluminous group velocity. In the massless Wess-Zumino model the minimum of the dispersion relation is at non zero momentum for temperatures above T-0 approximate to (g theta) (-1/2). We briefly comment on N = 2 Yang-Mills at finite density.
