Floquet-induced suppression of thermalization in a quasiperiodic Ising chain
Biswajit Paul, Nilanjan Roy, Tapan Mishra
Many-body localized (MBL) systems are known to thermalize in periodically driven systems. In this work, we demonstrate that under proper driving protocol, this thermalization this…
Emergent criticality in the Aubry-André model with periodic modulation
Sitaram Maity, Nilanjan Roy, Tapan Mishra
The Aubry-André model describes a system with quasiperiodic lattice modulation. In one dimension the AAH model is known to exhibit a sharp metal to insulator transition at a self-…
Robust translational invariance in topological bands against lattice potentials and disorders
Bo Peng, Nilanjan Roy, Guangyue Ji +1
We theoretically show that the continuous magnetic translational invariance within the Hilbert (sub-)space of a single Landau level (LL) can persist even in the presence of a super…
Superlattice induced electron percolation within a single Landau level
Nilanjan Roy, Bo Peng, Bo Yang
We investigate the quantum Hall effect in a single Landau level in the presence of a square superlattice of -function potentials. The interplay between the superlattice spacing…
