Taming entanglement in out-of-equilibrium quantum matter – TamEnt

Submission summary

Entanglement is the most distinctive and counter-intuitive feature of quantum mechanics. Recently, it has been used to characterize special phases of matter and transitions. In addition, entanglement represents the main limitation to the simulation of quantum matter on ordinary computers. In this project, we study entanglement production mechanisms in out of equilibrium quantum systems. We consider in particular the different microscopic structures that can take entanglement, which are associated with fundamental aspects of dynamics, whether chaotic or integrable. We develop new numerical methods that simulate systems in which entanglement is carried by pairs of stable quasiparticles. This provides the opportunity to address the crossover to chaos and the role of disorder in slowing down entanglement production and breaking ergodicity. We also analyze the role of measurement and feedback as tools to externally control quantum evolution
