T the fact that it really is flying by way of a cavity. We are going to show that the regimes exactly where 1 finds Unruh effect in cavities (defined as thermalization from the probe to a temperature proportional to its acceleration when interacting using the vacuum) are precisely those regimes where the probe can not resolve information about the impact from the cavity walls. In summary, we are going to show that you will find regimes where the probe is blind towards the fact that it truly is in a cavity and so experiences thermalization as outlined by Unruh’s law.Symmetry 2021, 13,III.
