Analytical and semianalytical tools to determine the topological character of Shiba chains
Nicholas Sedlmayr, Vardan Kaladzhyan, Cristina Bena
We introduce three new analytical and semi-analytical tools that allow one to determine the topological character of impurity Shiba chains. The analytical methods are based on calc…
Majorana fermions in finite-size strips in the presence of orbital effects: what is the Majorana polarization telling us?
Selma Franca, Vardan Kaladzhyan, Cristina Bena
We study numerically the formation of Majorana bound states in a finite-size quasi-one-dimensional square-lattice strip with Rashba spin-orbit coupling, in the presence of a proxim…
Topology from Triviality
Vardan Kaladzhyan, Cristina Bena, Pascal Simon
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…
Formation of Majorana fermions in finite-size graphene strips
Vardan Kaladzhyan, Cristina Bena
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…
