Thermal Wightman Functions and Renormalized Stress Tensors in the Rindler Wedge

TL;DR

This paper derives thermal Wightman functions and discusses the renormalized stress tensor in the Rindler wedge, highlighting gauge ambiguities for vector fields, contributing to quantum field theory in curved spacetime.

Contribution

It provides explicit expressions for thermal Wightman functions for massless fields up to spin 1 in the Rindler wedge and analyzes the associated stress tensor, including gauge issues.

Findings

Wightman functions derived for any temperature in the Rindler wedge.

Renormalized stress tensor discussed relative to Minkowski vacuum.

Gauge ambiguity identified in the vector field case.

Abstract

The Wightman functions in the Rindler portion of Minkowski space-time are presented for any value of the temperature and for massless spin fields up to s=1 and the renormalized stress tensor relative to Minkowski vacuum is discussed. A gauge ambiguity in the vector case is pointed out.
