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…
