False vacuum decay and metastability

Many systems in nature can remain for a long time in states far from equilibrium, such as supercooled water or the magnetic memory in our computers. This occurs when the system becomes trapped in a local energy minimum. In our research, we focus on understanding how such metastable behavior can arise in quantum many-body systems.
