Monitored free fermions under periodic driving

Aditi Chakrabarty, Alexander D. Mirlin, Igor Poboiko

We investigate analytically and numerically a one-dimensional periodically driven free-fermionic system subjected to monitoring of the local particle density. Based on the analytic…

Quantum dynamics of monitored free fermions: Evolution of quantum correlations and scaling at measurement-induced phase transition

Igor Poboiko, Alexander D. Mirlin

We explore, both analytically and numerically, the quantum dynamics of a many-body free-fermion system subjected to local density measurements. We begin by extending the mapping to…

Non-equilibrium bosonization of fractional quantum Hall edges

Christian Spånslätt, Jinhong Park, Alexander D. Mirlin

Edge transport serves as a powerful probe of remarkable low-energy properties of fractional quantum Hall states, including the anyonic character of their excitations. Here, we deve…

Measurement-induced Lévy flights of quantum information

Igor Poboiko, Marcin Szyniszewski, Christopher J. Turner +3

We explore a model of free fermions in one dimension, subject to frustrated (non-commuting) local measurements across adjacent sites, which resolves the fermions into non-orthogona…

Mesoscopic Fluctuations and Multifractality at and across Measurement-Induced Phase Transition

Igor Poboiko, Igor V. Gornyi, Alexander D. Mirlin

We explore statistical fluctuations over the ensemble of quantum trajectories in a model of two-dimensional free fermions subject to projective monitoring of local charge across th…

Scaling of many-body localization transitions: Quantum dynamics in Fock space and real space

Thibault Scoquart, Igor V. Gornyi, Alexander D. Mirlin

Many-body-localization (MBL) transitions are studied in a family of single-spin-flip spin- models, including the one-dimensional (1D) chain with nearest-neighbor interacti…
