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…
Topological boundaries in non-Hermitian p-wave Kitaev chains with Rashba spin-orbit coupling
Shahroze Shahab, Aditi Chakrabarty, Sanjoy Datta
In this work, we investigate the combined effects of Rashba spin-orbit coupling (RSOC) and non-Hermiticity on topological phase transitions in spinful p-wave Kitaev chains. While p…
Emergence of non-trivial phases in interacting non-Hermitian quasiperiodic chains with power-law hopping
Aditi Chakrabarty, Sanchayan Banerjee, Tapan Mishra +1
In the last few years, several works have identified the concurrence of the spectral, delocalization-localization and topological phase transitions in non-Hermitian quasiperiodic s…
The fate of Wannier-Stark localization and skin effect in periodically driven non-Hermitian quasiperiodic lattices
Aditi Chakrabarty, Sanjoy Datta
The eigenstates of one-dimensional Hermitian and non-Hermitian tight-binding systems (in the presence/absence of quasiperiodic potential) and an external electric field undergo com…
Engineering unique localization transition with coupled Hatano-Nelson chains
Ritaban Samanta, Aditi Chakrabarty, Sanjoy Datta
The Hatano-Nelson (HN) Hamiltonian has played a pivotal role in catalyzing research interest in non-Hermitian systems, primarily because it showcases unique physical phenomena that…
Extended unitarity and absence of skin effect in periodically driven systems
Aditi Chakrabarty, Sanjoy Datta
One of the most striking features of non-Hermitian quasiperiodic systems with arbitrarily small asymmetry in the hopping amplitudes and open boundaries is the accumulation of all t…
