Thermalisation as Diffusion in Hilbert Space

Aleksey Lunkin

We develop a microscopic theory of thermalisation for a thermometer coupled to a many-body bath beyond standard Markovian and Fermi-golden-rule assumptions. By modeling interaction…

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 for Lévy-Rosenzweig-Porter random matrix ensemble in the non-ergodic extended phase. Using an extension of Efetov's…
