V. Moretti et L. Vanzo, THERMAL WIGHTMAN FUNCTIONS AND RENORMALIZED STRESS TENSORS IN THE RINDLER WEDGE, Physics letters. Section B, 375(1-4), 1996, pp. 54-59
The Wightman functions in the Rindler portion of Minkowski space-time
are presented for any value of the temperature and for massless spin f
ields up to s = 1 and the renormalized stress tensor relative to Minko
wski vacuum is discussed. A gauge ambiguity in the victor case is poin
ted out.
