Abstract :

A many-body closed system may be unable to explore its whole available configuration space and fail to behave as predicted by Statistical Mechanics. This happens for a many-body localized state. Furthermore, it can also occur in a metallic regime. In this talk, I will show that certain Josephson Junction Arrays display a novel high temperature non-ergodic phase. With further increase of the temperature the system undergoes a transition to the fully localized state characterized by infinite resistance and exponentially long relaxation.
