Probing interacting many-body systems far from thermal equilibrium
The concept of thermodynamic equilibrium is fundamental to a modern understanding of interacting many-body systems. However, quantum systems isolated from the environment challenge textbook wisdom as they fail to reach thermal equilibrium and manage to retain a memory of their initial condition in local observables for an infinite amount of time. This dynamical phenomenon occurring in isolated many-body quantum systems is known as many-body localisation. The EU-funded MBL-Fermions project aims to enhance understanding of this phenomenon. It plans to study many-body localisation at tilted lattices, characterise the localisation properties using bipartite fluctuations and use a quantum simulator with more than 100 lattice sites to advance theories on interacting many-body systems.
