Understanding Thermodynamics Through Quantum Eigenstates
Department of Physics
There is a long quest on understanding how thermodynamics and statistical physics emerge from the microscopic laws of Nature dating back to Boltzmann. While in classical systems it is fairly well established that non-linear equations of motion lead to chaotic behavior of trajectories and as a result to ergodicity, in quantum systems equations of motion are linear and there is no chaos in the same sense. Chaos in quantum systems was progressively understood due to seminal contributions by J. von Neumann, E. Wigner, M. Berry and others. Finally about 20 years ago, a powerful conjecture allowing us to understand thermalization in quantum systems through eigenstates was formulated by J. Deutsch and M. Srednicki. This conjecture is now known as the Eigenstate Thermalization Hypothesis (ETH). In this talk I will review these developments and explain how one can understand many equilibrium and non-equilibrium thermodynamic relations (detailed balance, fluctuation theorems, Onsager relations and others). I will finish my talk by showing how using ETH, P. Ponte et al. made new non-perturbative predictions about periodically driven Floquet systems.
Physics and Astronomy Colloquia are usually scheduled for Thursdays at 4:10 PM in Lewis Lab room 316 (though this one will be held in LL 512). Refreshments and snacks are available in the nearby coffee room at 3:45 PM.
