Detecting coupling of Majorana bound states with an Aharonov-Bohm interferometer
J. P. Ramos-Andrade, P. A. Orellana, S. E. Ulloa
We study the transport properties of an interferometer composed by a quantum dot (QD) coupled with two normal leads and two one-dimensional topological superconductor nanowires (TN…
Thermoelectric transport through Majorana bound states and violation of Wiedemann-Franz law
J. P. Ramos-Andrade, O. Ávalos-Ovando, P. A. Orellana +1
We study features of the thermoelectric transport through a Kitaev chain hosting Majorana bound states (MBS) at its ends. We describe the behavior of the Seebeck coefficient and th…
Magnetic field induced mixed-level Kondo effect in two-level systems
Arturo Wong, Anh T. Ngo, Sergio E. Ulloa
We consider a two-orbital impurity system with intra and inter-level Coulomb repulsion that is coupled to a single conduction channel. This situation can generically occur in multi…
Edge states in dichalcogenide nanoribbons and triangular quantum dots
C. Segarra, J. Planelles, S. E. Ulloa
The electronic structure of monolayer MoS nanoribbons and quantum dots have been investigated by means of an effective two-band model. Both systems…
Berry phase and Rashba fields in quantum rings in tilted magnetic field
V. Lopes-Oliveira, L. K. Castelano, G. E. Marques +2
We study the role of different orientations of an applied magnetic field as well as the interplay of structural asymmetries on the characteristics of eigenstates in a quantum ring…
Currents and pseudomagnetic fields in strained graphene rings
D. Faria, A. Latge, S. E. Ulloa +1
We study the effects of strain on the electronic properties and persistent current characteristics of a graphene ring using the Dirac representation. For a slightly deformed graphe…
