Local reversibility and entanglement structure of many-body ground states

Abstract:

The low-temperature physics of quantum many-body systems is largely governed by the structure of their ground states. Minimizing the energy of local interactions, ground states often reflect strong properties of locality such as the area law for entanglement entropy and the exponential decay of correlations between spatially separated observables. Here, we present a novel characterization of quantum states, which we call 'local reversibility'. It characterizes the type of operations that are ...
