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

We investigate a recently proposed one-to-one correspondence between quantum field theories in twodimensional 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.
