Simulating Hawking radiation in quantum many-body systems: deviations from the thermal spectrum

TL;DR

This paper explores how quantum many-body systems can simulate Hawking radiation, revealing observable deviations from the expected thermal spectrum, thus providing insights into black hole physics through quantum simulations.

Contribution

It introduces a correspondence between 2D quantum field theories in curved spacetime and many-body systems, enabling simulation of Hawking radiation and observation of spectrum deviations.

Findings

Deviations from thermal spectrum are observable in many-body simulations.

The correspondence allows for studying black hole radiation in laboratory systems.

Simulation results align with tunneling method predictions.

Abstract

We investigate a recently proposed one-to-one correspondence between quantum field theories in two-dimensional curved spacetime and quantum many-body systems, which enables the simulation of Hawking radiation in static background spacetimes. In particular, we demonstrate that deviations from the thermal spectrum, as predicted by the well-known tunneling method, can be observed in many-body simulations.
