Tunable Floquet selection rules in a driven Ising chain
Rishi Paresh Joshi, Sanchayan Banerjee, Sneha Narasimha Moorthy +1
We study a periodically driven spin- Ising chain with a nearest-neighbour coupling and longitudinal field while a weak transverse field induces single-spin flips. Through Floq…
Non-Hermitian comb effect in coupled clean and quasiperiodic chains
Soumya Ranjan Padhi, Souvik Roy, Biswajit Paul +2
We study localization properties in a system of non-Hermitian quasiperiodic chain coupled to a uniform chain or clean chain by inter-chain hopping. We find that in the limit of wea…
Multiple many-body localization transitions in a driven non-Hermitian quasiperiodic chain
Sanchayan Banerjee, Ayan Banerjee, Tapan Mishra +1
We investigate the fate of a many-body localized phase in a non-Hermitian quasiperiodic model of hardcore bosons subjected to periodic driving. While in general, the many-body loca…
Reentrant topology and reverse pumping in a quasiperiodic flux ladder
Sanchayan Banerjee, Rajashri Parida, Tapan Mishra
Topological phases of matter are known to be unstable against strong onsite disorder in one dimension. In this work, however, we propose that in the case of a topological ladder, a…
Emergence of distinct exact mobility edges in a quasiperiodic chain
Sanchayan Banerjee, Soumya Ranjan Padhi, Tapan Mishra
Mobility edges (MEs) constitute the energies separating the localized states from the extended ones in disordered systems. Going beyond this conventional definition, recent proposa…
Anomalous spectrum in a non-Hermitian quasiperiodic chain
Soumya Ranjan Padhi, Sanchayan Banerjee, Tanay Nag +1
The spectra of particles in disordered lattices can either be completely extended or localized or can be intermediate which hosts both the localized and extended states separated f…
