| Summary: | The Unruh effect is a quantum relativistic effect where the accelerated
observer perceives the vacuum as a thermal state. Here we propose the
experimental realization of the Unruh effect for interacting ultracold fermions
in optical lattices by a sudden quench resulting in vacuum acceleration with
varying interactions strengths in the real temperature background. We observe
the inversion of statistics for the low lying excitations in the Wightman
function as a result of competition between the spacetime and BCS Bogoliubov
transformations. This paper opens up new perspectives for simulators of quantum
gravity. |
