Entanglement asymmetry for boosted black branes

TL;DR

This paper investigates how boosting black brane backgrounds influence entanglement thermodynamics in conformal field theories, revealing the role of pressure and subsystem orientation, with implications for universal bounds in AdS-wave backgrounds.

Contribution

It introduces the concept of entanglement asymmetry in boosted black branes and analyzes the effects of boost direction on entanglement thermodynamics in CFT subsystems.

Findings

Boosted p-branes induce a first law of entanglement thermodynamics with pressure effects.

Subsystem orientation relative to the boost affects entanglement properties.

Universal bounds are discussed in the context of AdS-wave backgrounds.

Abstract

We study the effects of asymmetry in entanglement thermodynamics of the CFT subsystems. It is found that `boosted' $p$-branes backgrounds give rise to the first law of the entanglement thermodynamics where the CFT pressure plays decisive role in the entanglement. Two different strip like subsystems, one parallel to the boost and the other perpendicular, are studied in the perturbative regime, where $T_{thermal}\ll T_E$. We also discuss the AdS-wave backgrounds where some universal bounds can be obtained.
