Classicality, Markovianity and local detailed balance in isolated quantum systems — •Philipp Strasberg — Instituto de Física de Cantabria (IFCA), Santander, Spain

This poster reviews how the familiar description of stochastic thermodynamics, based on classical Markov processes obeying local detailed balance, emerges from an underlying quantum description from first principles. Here, "first principles" means that we avoid ensemble averages and any assumptions breaking the unitarity of the underlying quantum dynamics (e.g., Born or Markov approximations). Connections to a general approach of thermodynamic entropy (production) and the structure of the Multiverse are also indicated.

Keywords: pure state statistical mechanics; Markovianity; local detailed balance; decoherence; eigenstate thermalization hypothesis
