Circular Rosenzweig-Porter random matrix ensemble
Wouter Buijsman, Yevgeny Bar Lev
The Rosenzweig-Porter random matrix ensemble serves as a qualitative phenomenological model for the level statistics and fractality of eigenstates across the many-body localization…

Dissipation-Stabilized Quantum Revivals in a Non-Hermitian Lattice Gauge Theory
Yevgeny Bar Lev, Jad C. Halimeh, Achilleas Lazarides
With the advent of quantum simulation experiments of lattice gauge theories (LGTs), an open question is the effect of non-Hermiticity on their rich physics. The well-known PXP mode…

Heavy-Tailed Hall Conductivity Fluctuations in Quantum Hall Transitions
Emuna Rimon, Eytan Grosfeld, Yevgeny Bar Lev
We study the full distribution of the zero-temperature Hall conductivity in a lattice model of the IQHE using the Kubo formula across disorder realizations. Near the localization-d…
