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…
Measurement-induced phase transition for free fermions above one dimension
Igor Poboiko, Igor V. Gornyi, Alexander D. Mirlin
A theory of the measurement-induced entanglement phase transition for free-fermion models in dimensions is developed. The critical point separates a gapless phase with $\ell^…
