We study an atom-cavity hybrid system where fermionic atoms in a one-dimensional lattice are subject to cavity-induced dynamic gauge potential. The coupling leads highly degenerate steady states which the fermions accumulate one edge of under open boundary condition. Such phenomenon originates from many-body Liouvillian superoperator system, which, being intrinsically non-Hermitian, is unstable...

In networked systems, initial failures at only a small part of the network may trigger sequential failure process called cascading failures, which eventually lead to breakdown entire system. This vulnerability is further exacerbated in modern systems that consist multiple networks, each carryin...
