Müller, Markus, Philipp Strack, and Subir Sachdev. 2012. Quantum charge glasses of itinerant fermions with cavity-mediated long-range interactions. Physical Review A 86(2): 023604.Abstract
We study models of itinerant spinless fermions with random long-range interactions. We motivate such models from descriptions of fermionic atoms in multimode optical cavities. The solution of an infinite-range model yields a metallic phase, which has glassy charge dynamics, and a localized glass phase with suppressed density of states at low energies. We compare these phases to the conventional disordered Fermi liquid, and the insulating electron glass of semiconductors. Prospects for the realization of such glassy phases in cold-atom systems are discussed.Other Sources
