A Note on the Generalization of the GEMS Approach

TL;DR

This paper explores how the GEMS approach maps the vector potential of charged black holes, showing it induces a chemical potential in the thermal spectrum, but argues that extending GEMS to non-stationary motions is not feasible.

Contribution

It demonstrates the effect of vector potentials on GEMS mapping and thermal spectra, and discusses the limitations of extending GEMS to non-stationary cases.

Findings

Vector potential induces a chemical potential in the thermal spectrum.

GEMS approach maps the vector potential effects consistently.

Extension to non-stationary motions is not possible.

Abstract

This paper is a supplement of our earlier work JHEP 0410 (2004) 011[gr-qc/0409107].We map the vector potential of charged black holes into GEMS and find that its effect on the thermal spectrum is the same as that on the black hole side, i.e., it will induce a chemical potential in the thermal spectrum which is the same as that in the charged black holes.We also argue that the generalization of GEMS approach to non-stationary motions is not possible.
