Engineering electronic states of periodic and quasiperiodic chains by buckling
Amrita Mukherjee, Atanu Nandy, Arunava Chakrabarti
The spectrum of spinless, non-interacting electrons on a linear chain that is buckled in a non- uniform manner giving it a flavor of a topologically disordered lattice, is investig…
Phase controlled metal-insulator transition in multi-leg quasiperiodic optical lattices
Santanu K. Maiti, Shreekantha Sil, Arunava Chakrabarti
A tight-binding model of a multi-leg ladder network with a continuous quasiperiodic modulation in both the site potential and the inter-arm hopping integral is considered. The mode…
Controlled delocalization of electronic states in a multi-strand quasiperiodic lattice
Amrita Mukherjee, Atanu Nandy, Arunava Chakrabarti
Finite strips, composed of a periodic stacking of infinite quasiperiodic Fibonacci chains, have been investigated in terms of their electronic properties. The system is described b…
Tight-binding chains with off-diagonal disorder: Bands of extended electronic states induced by minimal quasi-one dimensionality
Atanu Nandy, Biplab Pal, Arunava Chakrabarti
It is shown that, an entire class of off-diagonally disordered linear lattices composed of two basic building blocks and described within a tight binding model can be tailored to g…
Spin filter for arbitrary spins by substrate engineering
Biplab Pal, Rudolf A. Römer, Arunava Chakrabarti
We design spin filters for particles with potentially arbitrary spin S (= 1/2, 1, 3/2,....) using a one-dimensional periodic chain of magnetic atoms as a quantum device. Describing…
