In the present work, the possibility of regulating local magnetic field in a quantum ring is
investigated theoretically. The ring is coupled to a quantum wire and subjected to an in …

The quest for Majorana zero modes in the laboratory is an active field of research in
condensed matter physics. In this regard, there have been many theoretical proposals; …

The robust effect of curvature on spin polarization is reported in a three-terminal bridge
system where the bridging material is subjected to Rashba spin–orbit interaction. The results …

An essential attribute of many fractal structures is self-similarity. A Sierpinski gasket (SPG)
triangle is a promising example of a fractal lattice that exhibits localized energy eigenstates …

In this article we study the role of Rashba spin–orbit coupling and electron–phonon
interaction on the electronic structure of zigzag graphene nanoribbon with different width …

We show that a tight-binding one-dimensional chain composed of interacting and non-
interacting atomic sites can exhibit multiple mobility edges at different values of carrier …

Transport through a nano-device in the presence of electron–phonon interaction has been
studied by using unitary-transformation scheme together with the non-equilibrium Green׳ s …

Fractal geometry presents us with a self-similarity in their pattern at various length scales
that is prevalent in our natural world. We present theoretical model of a Sierpinski gasket …

The key requirement for an enhanced thermoelectric (TE) performance is the presence of
asymmetry in transmission function. Focussing on this issue, we propose a unique idea to …

In this paper we consider the system composed of two magnetic planes attached to zigzag
terminations of the graphene nanostructure being an ultrashort fragment of the armchair …
