TL;DR

This paper introduces new analytic solutions for accelerating mirrors in Minkowski spacetime, providing insights into the dynamical Casimir effect, black hole analogs, and entanglement entropy through detailed analysis of particle, energy, and entropy production.

Contribution

It presents novel symmetric and analytic moving mirror solutions, including an asymptotically static case with finite emission and a drifting analog, advancing understanding of black hole evaporation and remnants.

Findings

Finite energy and entropy emission in the static mirror case.

Spectrum and particle production are symmetric on both sides of the mirror.

The drifting mirror models black hole remnants with finite particle production.

Abstract

Radiation from accelerating mirrors in a Minkowski spacetime provides insights into the nature of horizons, black holes, and entanglement entropy. We introduce new, simple, symmetric and analytic moving mirror solutions and study their particle, energy, and entropy production. This includes an asymptotically static case with finite emission that is the black hole analog of complete evaporation. The total energy, total entropy, total particles, and spectrum are the same on both sides of the mirror. We also study its asymptotically inertial, drifting analog (which gives a black hole remnant) to explore differences in finite and infinite production.
