Title: Quantum Joule Paddle Bucket from thermometry to transport

Abstract: Joule’s paddle bucket experiment was one of the defining experiments of 19th century physics demonstrating the mechanical equivalent of heat. Can we think about this experiment from the perspective of pure quantum mechanics. In this talk I will demonstrate how the original concept by Joule serves as an inspiration for a novel quantum thermometry scheme based on the eigenstate thermalization hypothesis where the system remains in a pure quantum state. I will then motivate how the same idea can be used to inspire techniques to probe high temperature transport in spin systems on both analogue and digital simulators.
