Quantum Informational Analogue Models of Black Holes

Black holes are extremely efficient storer of quantum information. In this talk, we investigate a universal mechanism underlying the microscopic origin of this enhanced microstate entropy. Moreover, we implement this mechanism in simple condensed matter inspired models and study their dynamical properties. We argue that such systems are subjected to the universal effect of memory burden, which ties them to a critical state and suppresses their decay. Finally, we discuss implications to cosmology and black hole evolution.
