Entanglement Harvesting with Moving Mirrors

TL;DR

This paper investigates how moving mirrors in a 1+1 dimensional spacetime affect entanglement harvesting from the vacuum, revealing both inhibition and enhancement effects depending on mirror trajectories.

Contribution

It introduces a detailed analysis of entanglement harvesting with moving mirrors, including various trajectories and detector couplings, highlighting phenomena similar to black hole effects.

Findings

Entanglement inhibition similar to black hole phenomena.

Trajectory-independent entanglement enhancement in certain regimes.

Qualitative results consistent across different detector couplings.

Abstract

We study the phenomenon of entanglement extraction from the vacuum of a massless scalar field in $(1+1)$ dimensional spacetime in presence of a moving Dirichlet boundary condition, i.e. mirror spacetime, using two inertial Unruh-DeWitt detectors. We consider a variety of non-trivial trajectories for these accelerating mirrors and find (1) an entanglement inhibition phenomenon similar to that recently seen for black holes, as well as (2) trajectory-independent entanglement enhancement in some regimes. We show that the qualitative result obtained is the same for both linear and derivative couplings of the detector with the field.
