TL;DR
This paper constructs and analyzes quantum states of a massless scalar field in various two-dimensional black hole spacetimes, calculating the renormalized energy-momentum tensor and discussing different quantum states.
Contribution
It provides a method to construct the Hartle-Hawking-Israel state and computes the renormalized energy-momentum tensor in multiple two-dimensional black hole backgrounds.
Findings
Explicit construction of Hartle-Hawking-Israel state in 2D BTZ black hole
Calculation of renormalized energy-momentum tensor in CGHS, AdS, RW, and Rindler spacetimes
Discussion of Boulware, Hartle-Hawking-Israel, and Unruh states in 2D black holes
Abstract
We point out how to construct the Hartle-Hawking-Israel state for the minimaly coupled massless quantum real scalar field in the two dimensional BTZ black hole. We also calculate the renormalized energy-momentum tensor for the same field in the eternal CGHS black hole, AdS, Robertson-Walker and Rindler spacetime in two dimensions. We also discuss the Boulware, the Hartle-Hawking-Israel and the Unruh state for the eternal CGHS black hole.
