TL;DR
This paper derives exact formulas for quantum radiation emitted by a partially reflecting moving mirror in 1+1 dimensions, accounting for arbitrary mirror trajectories and partial reflectivity effects.
Contribution
It provides a novel exact integral expression for the radiated flux from a partially reflecting mirror with arbitrary motion in 1+1 Minkowski space.
Findings
Exact radiated flux formulas for arbitrary mirror trajectories.
Partial reflectivity modifies the perfect mirror radiation results.
The approach models partial reflectivity via a delta potential at the mirror.
Abstract
We consider the quantum radiation from a partially reflecting moving mirror for the massless scalar field in 1+1 Minkowski space. Partial reflectivity is achieved by localizing a delta-type potential at the mirror's position. The radiated flux is exactly obtained for arbitrary motions as an integral functional of the mirror's past trajectory. Partial reflectivity corrections to the perfect mirror result are discussed.
