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…

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…

Tunneling current and current correlations for anyonic quasiparticles of ν = 1/2 chiral Luttinger liquid in multi-edge geometries

Gu Zhang, Domenico Giuliano, Igor V. Gornyi +1

We consider anyonic quasiparticles with charge e/2 described by the ν = 1/2 chiral Luttinger liquid, which collide in a Hong-Ou-Mandel-like interferometer. These colliding anyonic…
