Infrared gravity and a celestial obstruction to monogamy constraints

TL;DR

This paper proposes that gravitational interactions necessitate a revision of quantum state descriptions for multiparticle systems, introducing a new relativistic angular momentum charge that impacts entanglement constraints in black hole contexts.

Contribution

It introduces a novel framework incorporating a boost-like angular momentum charge, challenging traditional tensor product assumptions in quantum states under gravity.

Findings

Gravity induces a new angular momentum charge in multiparticle systems.

Standard quantum state tensor products are insufficient in gravitational contexts.

Implications for entanglement constraints in black hole physics.

Abstract

We argue that gravitational interactions between particles require a departure from the conventional picture of the quantum state of a multiparticle system in terms of tensor products of one-particle states. This modification is essential in order to accommodate the existence of a new boost-like relativistic angular momentum charge which pairs of particles must carry asymptotically due to long-range effects of gravity. These findings challenge conventional assumptions, prompting a reevaluation of the constraints on quantum entanglement between particle subsystems in a black hole geometry.
