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…
Flux-driven charge and spin transport in a dimerized Hubbard ring with Fibonacci modulation
Souvik Roy, Soumya Ranjan Padhi, Tapan Mishra
We study quantum transport in a one-dimensional Hubbard ring with dimerized nearest-neighbor hoppings and a Fibonacci-modulated onsite potential. For non-interacting case our analy…
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…
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…
Correlated hopping induced topological order in an atomic mixture
Ashirbad Padhan, Luca Barbiero, Tapan Mishra
The large majority of topological phases in one dimensional many-body systems are known to inherit from the corresponding single-particle Hamiltonian. In this work, we go beyond th…
