Nonminimal coupling and entropy interpretation

Verified source

Physical Review D 56 (1997), 4968-4974; arXiv:hep-th/9612061. The primary APS and arXiv abstracts describe a modified brick-wall/scattering prescription, agreement in the stated negative-coupling regime, and differing results for positive coupling.

Use and boundary

A scope warning for the RT effective-action calculation: a local replica/Wald contribution with nonminimal coupling is not automatically positive ordinary von Neumann matter entropy. The citation does not establish a general equality for all curvature couplings or all states.
