Doron Cohen (Ben-Gurion University of the Negev) | Quantum Irreversibility of Quasistatic Protocols |


In quantum mechanics, a driving process is expected to be reversible in the quasistatic limit, aka adiabatic theorem. This statement stands in opposition to classical mechanics, where mixed chaotic dynamics implies irreversibility in this limit. A paradigm for demonstrating the signatures of chaos in quantum irreversibility, is a sweep protocol whose objective is to transfer condensed bosons from a source orbital. As the sweep rate is lowered, a crossover to a chaos-assisted-depletion regime that is dominated by universal quantum fluctuations is encountered, featuring a breakdown of quantum-to-classical correspondence.
