Entanglement in quantum matter - thermalization and its absence
Speaker: Jens H Bárðarson, Royal Institute of Technology
Abstract: I will discuss the role entanglement plays in understanding the structure and dynamics of quantum matter. I will focus on a particular question: when do closed quantum systems thermalize? That is, when does statistical mechanics emerge from quantum mechanics. I will also discuss quantum information and its flow in prototypical example of quantum states. Much of the talk will be about visualising the structure of quantum information using the information lattice, a concept we recently introduced. Using this I will give a explanation of how the eigenstate thermalisation hypothesis explains thermalisation. While some of this sounds rather technical, I will attempt to be as pedagogical as possible.
