The first observation of a marginal Fermi glass

PHYS.ORG – Researchers at University of Illinois, Johns Hopkins University, CUNY College of Staten Island and University of Colorado Boulder have recently used a new technique they developed to investigate the possibility that a strongly disordered and highly correlated and disordered electron system (i.e., phosphorus-doped silicon) could be mapped to a system of non-interacting and localized excitations. Their experiments ultimately led to the observation of a unique phenomenon that they dubbed marginal Fermi glass. Read more at
