Density of states correlations in Lévy Rosenzweig-Porter model via supersymmetry approach

Elizaveta Safonova, Aleksey Lunkin, Mikhail Feigel' man

We studied global density-of-states correlation function $R(\omega )$ for Lévy-Rosenzweig-Porter random matrix ensemble in the non-ergodic extended phase. Using an extension of Efetov's…
