Reentrant localization transition, quantum butterfly and robust edge modes in aperiodic zig-zag ladder
Sayan Bhattacharya, Rhiddha Acharjee, Atanu Nandy
Low dimensional tight-binding lattices in presence of quasiperiodic disorder generally exhibits localization transition. The system supports diffusive modes upto a limiting strengt…

Localization, transport, flux induced extended modes and mobility edge in a self-similar corral substrate
Sayan Bhattacharya, Rhiddha Acharjee, Atanu Nandy
We address that a single-band tight-binding Hamiltonian defined on a self-similar corral substrate can give rise to a set of non-diffusive localized modes that follow the same hier…
