Engineering topological phase transition and Aharonov-Bohm caging in a flux-staggered lattice
Amrita Mukherjee, Atanu Nandy, Shreekantha Sil +1
A tight binding network of diamond shaped unit cells trapping a staggered magnetic flux distribution is shown to exhibit a topological phase transition under a controlled variation…
Spin-selective Aharonov-Casher caging in a topological quantum network
Amrita Mukherjee, Rudolf A. Romer, Arunava Chakrabarti
A periodic network of connected rhombii, mimicking a spintronic device, is shown to exhibit an intriguing spin selective extreme localization, when submerged in a uniform out of pl…
Flux modulated flat band engineering in square-kagome ladder network
Atanu Nandy, Amrita Mukherjee
The origin of non-dispersive flat band modes for a quasi-one dimensional square-kagome ladder network is explored analytically by virtue of the real space renormalization group (RS…
Spin-polarized localization in a magnetized chain
Leonardo Benini, Amrita Mukherjee, Arunava Chakrabarti +1
We investigate a simple tight-binding Hamiltonian to understand the stability of spin-polarized transport of states with an arbitrary spin content in the presence of disorder. The…
Flux driven and geometry controlled spin filtering for arbitrary spins in aperiodic quantum networks
Amrita Mukherjee, Arunava Chakrabarti, Rudolf A. Roemer
We demonstrate that an aperiodic array of certain quantum networks comprising magnetic and non-magnetic atoms can act as perfect spin filters for particles with arbitrary spin stat…
