T the fact that it is flying through a cavity. We’ll show that the regimes exactly where one finds Unruh effect in cavities (defined as thermalization from the probe to a temperature proportional to its acceleration when interacting together with the vacuum) are precisely those regimes exactly where the probe can not resolve information about the effect on the cavity walls. In summary, we will show that you can find regimes where the probe is blind towards the truth that it really is within a cavity and so experiences thermalization according to Unruh’s law.Symmetry 2021, 13,III.
