Anomalous transport in long-ranged open quantum systems

A Dhawan, K Ganguly, M Kulkarni, BK Agarwalla - Physical Review B, 2024 - APS
We consider a one-dimensional fermionic lattice system with long-ranged power-law
decaying hop** with exponent α. The system is further subjected to dephasing noise in …

Density and current statistics in boundary-driven monitored fermionic chains

X Turkeshi, L Piroli, M Schirò - Physical Review B, 2024 - APS
We consider a one-dimensional system of noninteracting fermions featuring both boundary
driving and continuous monitoring of the bulk particle density. Due to the measurements, the …

Keldysh nonlinear sigma model for a free-fermion gas under continuous measurements

Q Yang, Y Zuo, DE Liu - Physical Review Research, 2023 - APS
Quantum entanglement phase transitions have provided new insights into quantum many-
body dynamics. Both disorders and measurements are found to induce similar entanglement …

Measurements on an Anderson chain

P Pöpperl, IV Gornyi, Y Gefen - Physical Review B, 2023 - APS
We study the dynamics of a monitored single particle in a one-dimensional Anderson-
localized system. The time evolution is governed by Hamiltonian dynamics for fixed time …

Superdiffusive transport in quasi-particle dephasing models

YP Wang, C Fang, J Ren - SciPost Physics, 2024 - scipost.org
Investigating the behavior of noninteracting fermions subjected to local dephasing, we
reveal that quasi-particle dephasing can induce superdiffusive transport. This superdiffusion …

Impact of dephasing probes on incommensurate lattices

B Ghosh, S Mohanta, M Kulkarni… - Journal of Statistical …, 2024 - iopscience.iop.org
We investigate open quantum dynamics for a one-dimensional incommensurate Aubry–
André–Harper lattice chain, a part of which is initially filled with electrons and is further …
