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…

Unified strategy of flat band engineering, electronic transport and other spectral properties for different kagome ribbon variants
Atanu Nandy
We address the problem of flat band engineering in different prototypes of quasi-one dimensional kagome network through a generalized analytical proposition worked out within the t…
