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…
High degree of current rectification at nanoscale level
Madhumita Saha, Santanu K. Maiti
We address an unexpectedly large rectification using a simple quantum wire with correlated site potentials. The external electric field, associated with voltage bias, leads to uneq…
Modulation of circular current and associated magnetic field in a molecular junction: A new approach
Moumita Patra, Santanu K. Maiti
A new proposal is given to control local magnetic field in a molecular junction. In presence of finite bias a net circular current is established in the molecular ring which induce…
Magnetic response of non-interacting and interacting electrons in a Möbius strip
Madhumita Saha, Santanu K. Maiti
We investigate characteristic features of both non-interacting and interacting electrons in a Möbius strip, the simplest possible one-sided topological system, in presence of an Ah…
Characteristics of persistent spin current components in a quasi-periodic Fibonacci ring with spin-orbit interactions: Prediction of spin-orbit coupling and on-site energy
Moumita Patra, Santanu K. Maiti
In the present work we investigate the behavior of all three components of persistent spin current in a quasi-periodic Fibonacci ring subjected to Rashba and Dresselhaus spin-orbit…
Unconventional low-field magnetic response of a diffusive ring with spin-orbit coupling
Moumita Patra, Santanu K. Maiti
We report an unconventional behavior of electron transport in the limit of zero magnetic flux in a one-dimensional disordered ring, be it completely random or any correlated one, s…
