A Unified Framework for Locally Stable Phases
Zhi Li, Raz Firanko, Timothy H. Hsieh
We propose a unifying framework for characterizing pure and mixed state phases of matter across equilibrium, non equilibrium, and metastable regimes. We introduce the concept of lo…

Area laws and tensor networks for maximally mixed ground states
Itai Arad, Raz Firanko, Rahul Jain
We show an area law in the mutual information for the maximally-mixed state in the ground space of general Hamiltonians, which is independent of the underlying ground space de…

Local quantum channels giving rise to quasi-local Gibbs states
Itai Arad, Raz Firanko, Omer Gurevich
We study the steady-state properties of quantum channels with local Kraus operators. We consider a large family that consists of general ergodic 1-local (non-interacting) terms and…
