Quantum ergodicity in the many-body localization problem
Felipe Monteiro, Masaki Tezuka, Alexander Altland +2
We generalize Page's result on the entanglement entropy of random pure states to the many-body eigenstates of realistic disordered many-body systems subject to long range interacti…

A minimal model of many body localization
Felipe Monteiro, Tobias Micklitz, Masaki Tezuka +1
We present a fully analytical description of a many body localization (MBL) transition in a microscopically defined model. Its Hamiltonian is the sum of one- and two-body operators…

Non-ergodic extended states in the SYK model
T. Micklitz, Felipe Monteiro, Alexander Altland
We analytically study spectral correlations and many body wave functions of an SYK-model deformed by a one body contribution to the Hamiltonian. Our main result is the identificati…
