Quantum Matter Stuck in Unrest

Quantum Matter Stuck in Unrest

The initial charge ordered state (1) quickly looses its charge order under an ergodic dynamics (2) while retaining parts of it in the localized phase (3).

We have observed a novel state of matter that, despite being interacting, never thermalizes. Such Many-Body Localized States represent a new class of systems that fail to be described by standard thermodynamics and statistical physics and require new theoretical and experimental approaches to characterize them.
