  author={Vardan Kaladzhyan and Cristina Bena},
  journal={arXiv: Superconductivity},
We investigate the formation of Majorana fermions in finite-size graphene strips with open boundary conditions in both directions, in the presence of an in-plane magnetic field and in the proximity of a superconducting substrate. We show that for long enough strips the Majorana states can form in the presence of a Rashba-like spin-orbit coupling, as well as in the presence of an inhomogeneous magnetic field. We find that, unlike infinite graphene ribbons in which Majorana states arise solely… 
Suppression of the overlap between Majorana fermions by orbital magnetic effects in semiconducting-superconducting nanowires
We study both analytically and numerically the role of orbital effects caused by a magnetic field applied along the axis of a semiconducting Rashba nanowire in the topological regime hosting Majorana
Majorana bound states in a superconducting Rashba nanowire in the presence of antiferromagnetic order
Theoretical studies have shown that Majorana bound states can be induced at the ends of a one-dimensional wire, a phenomenon possible due to the interplay between $s$-wave superconductivity,
Bending effect on the Majorana bound states in planar Josephson junctions
We consider the bending effect on the formation of Majorana bound states (MBSs) in planar Josephson junctions where the normal stripe is tilted in a V shape. Our results show that the MBSs remain
Efficient identification of Majorana modes in large tight-binding systems
Low dimensional structures in the non-trivial topological phase can host the in-gap Majorana bound states identified experimentally as zero-bias peaks in differential conductance. Theoretical methods
Topology from triviality
We show that bringing into proximity two topologically trivial systems can give rise to a topological phase. More specifically, we study a 1D metallic nanowire proximitized by a 2D superconducting ...

Majorana fermions in honeycomb lattices
We study the formation of Majorana fermions in honeycomb-lattice structures in the presence of a Zeeman field, Rashba spin-orbit coupling, and in the proximity of an s-wave superconductor. We show
Majorana Zero Modes in Graphene
A clear demonstration of topological superconductivity (TS) and Majorana zero modes remains one of the major pending goal in the field of topological materials. One common strategy to generate TS is
Giant Spin-Orbit Interaction Due to Rotating Magnetic Fields in Graphene Nanoribbons
We study graphene nanoribbons theoretically in the presence of spatially varying magnetic fields produced, e.g., by nanomagnets. We show, both analytically and numerically, that an exceptionally
Majorana fermions and a topological phase transition in semiconductor-superconductor heterostructures.
The measurement of the supercurrent through the junction allows one to discern topologically distinct phases and observe a topological phase transition by simply changing the in-plane magnetic field or the gate voltage, which will be a direct demonstration of the existence of Majorana particles.
Quantum spin Hall effect in graphene.
Graphene is converted from an ideal two-dimensional semimetallic state to a quantum spin Hall insulator and the spin and charge conductances in these edge states are calculated and the effects of temperature, chemical potential, Rashba coupling, disorder, and symmetry breaking fields are discussed.
Spin-orbit splitting in graphene on metallic substrates.
The small spin-orbit splitting induced by the Ag substrates indicates that heavy metals do not always produce large SO splitting, and provides important insights that are useful for understanding the metal-induced Rashba effect in graphene.

Starting from a microscopic tight-binding model and using second-order perturbation theory, we derive explicit expressions for the intrinsic and Rashba spin-orbit interaction induced gaps in the

In a variety of rare-earth-based compounds, singlet superconductivity coexists with helical magnetism. Here we demonstrate that surfaces of these systems should generically host a finite density of

We theoretically investigate the effect of intertube tunneling in topological superfluid phases of a quasi-one-dimensional Fermi gas with a Rashba-type spin–orbit interaction. It is shown that the
