Thermality of circular motion, in spacetime and in the laboratory
Abstract: The celebrated Unruh effect states that observers in uniform linear acceleration experience Minkowski vacuum in relativistic quantum field theory as a thermal state, in a temperature proportional to the proper acceleration. Observers in uniform circular acceleration experience a similar effect, with a more subtle notion of an effective temperature, but, crucially, with better prospects of experimental verification, especially so in condensed matter analogue spacetime systems that are realisable in the laboratory. This talk reviews the theoretical distinctions between linear and circular acceleration and the recent experimental proposals to observe the circular motion Unruh effect in the laboratory. The talk is based on 2007.09523, 2007.07160 and 2302.12023. - Tuesday 24 October 2023 at 10:15 in A315 and using Zoom: Tuomo Salmi (Amsterdam)
