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…
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 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…
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…
Mean-field theory of first-order quantum superconductor-insulator transition
Igor Poboiko, Mikhail Feigel'man
Recent experimental studies on strongly disordered indium oxide films have revealed an unusual first-order quantum phase transition between the superconducting and insulating state…
First-order quantum breakdown of superconductivity in amorphous superconductors
Thibault Charpentier, David Perconte, Sébastien Léger +10
Continuous quantum phase transitions are widely assumed and frequently observed in various systems of quantum particles or spins. Their characteristic trait involves scaling laws g…
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^…
Theory of free fermions under random projective measurements
Igor Poboiko, Paul Pöpperl, Igor V. Gornyi +1
We develop an analytical approach to the study of one-dimensional free fermions subject to random projective measurements of local site occupation numbers, based on the Keldysh pat…
Paraconductivity of pseudogapped superconductors
Igor Poboiko, Mikhail Feigel'man
We calculate Aslamazov-Larkin paraconductity for a model of strongly disordered superconductors (dimensions ) with a large pseudogap whose magnitude strongly exc…
Spin correlation functions and quasiparticle decay
Igor Poboiko, Mikhail Feigel'man
We study one-dimensional anisotropic XXZ spin- model with ferromagnetic sign of the coupling and exchange constant , where , and is the coupling…
Thermal transport in disordered one-dimensional spin chains
Igor Poboiko, Mikhail Feigel'man
We study one-dimensional anisotropic XY-Heisenberg spin- chain with weak random fields by means of Jordan-Wigner transformation to spinless Luttinger liq…
