Anomalous response, re-emerging localization-transition and robust corner sates in self-similar peano fractal
Rhiddha Acharjee, Sayan Bhattacharya, Atanu Nandy +1
Anomalous spectral response from the non-interacting electrons on a peano fractal is recorded within tight-binding framework. It is observed that a minimal off-diagonal anisotropy…

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…
