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…
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…
Measurement-induced transitions for interacting fermions
Igor Poboiko, Paul Pöpperl, Igor V. Gornyi +1
Effect of measurements on interacting fermionic systems with particle-number conservation, whose dynamics is governed by a time-independent Hamiltonian, is studied. We develop Keld…
