Exact analytical solution of a time-reversal-invariant topological superconducting wire
Armando A. Aligia, Alberto Camjayi
We consider a model proposed before for a time-reversal-invariant topological superconductor (TRITOPS) which contains a hopping term , a chemical potential , an extended -…
Catalogue of Andreev spectra and Josephson effects in structures with time-reversal-invariant topological superconductor wires
Liliana Arrachea, Alberto Camjayi, Armando A. Aligia +1
We study all the possible different two terminal configurations of Josephson junctions containing wires of time-reversal invariant topological superconductors (TRITOPS) and ordinar…
Kondo behavior and conductance through impurities in gold chains doped with oxygen
M. A. Barral, S. Di Napoli, G. Blesio +4
Combining ab initio calculations and effective models derived from them, we discuss the electronic structure of oxygen doped gold chains when one Au atom is replaced by any transit…
Fractional spin and Josephson effect in time-reversal-invariant topological superconductors
Alberto Camjayi, Liliana Arrachea, Armando Aligia +1
Time reversal invariant topological superconducting (TRITOPS) wires are known to host a fractional spin hbar/4 at their ends. We investigate how this fractional spin affects the Jo…
Transport in quantum spin Hall edges in contact to a quantum dot
Bruno Rizzo, Alberto Camjayi, Liliana Arrachea
We study the transport mechanisms taking place in a quantum spin Hall bar with an embedded quantum dot, where electrons localize and experience Coulomb interaction U as well as spi…
Mesoscopic features in the transport properties of a Kondo-correlated quantum dot in a magnetic field
Alberto Camjayi, Liliana Arrachea
We study the transport behavior induced by a small bias voltage through a quantum dot connected to one-channel finite-size wires. We describe the quantum dot by the Hubbard-Kondo w…
