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-d…

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…
