Robust Signatures of Majorana Fermions in a Semiconductor Quantum Ring
Aram Manaselyan, Areg Ghazaryan, Tapash Chakraborty
We have investigated the possible presence of Majorana fermions in a semiconductor quantum ring containing a few interacting electrons, and a strong spin-orbit interaction, proximi…
Aspects of Anisotropic Fractional Quantum Hall Effect in Phosphorene
Areg Ghazaryan, Tapash Chakraborty
We have analyzed the effects of the anisotropic energy bands of phosphorene on magnetoroton branches for electrons and holes in the two Landau levels close to the band edges. We ha…
Long Range Coulomb Interaction and the Majorana Fermions
Areg Ghazaryan, Tapash Chakraborty
We have investigated the effects of long-range Coulomb interaction on the topological superconducting phase in a quasi-one dimensional semiconductor wire, proximity coupled to a s-…
Fractal Butterflies of Chiral Fermions in Bilayer Graphene: Phase Transitions and Emergent Properties
Areg Ghazaryan, Tapash Chakraborty
We report on our studies of fractal butterflies in biased bilayer graphene in the fractional quantum Hall effect (FQHE) regime. We have considered the case when the external period…
