Majoranas with and without a 'character': hybridization, braiding and Majorana number
N. Sedlmayr, M. Guigou, P. Simon +1
In this paper we demonstrate under what conditions a pseudo-spin degree of freedom or character can be ascribed to the Majorana bound states (MBS) which can be created at the end o…
Superconductor spintronics: Modeling spin and charge accumulation in out-of-equilibrium NS junctions subjected to Zeeman magnetic fields
D. Chevallier, M. Trif, C. Dutreix +4
We study the spin and charge accumulation in junctions between a superconductor and a ferromagnet or a normal metal in the presence of a Zeeman magnetic field, when the junction is…
Signature of a topological phase transition in long SN junctions in the spin-polarized density of states
M. Guigou, N. Sedlmayr, J. M. Aguiar-Hualde +1
We investigate the spin texture of Andreev bound states and Majorana states in long SN junctions. We show that measuring the spin-polarized density of states (SPDOS) allows one to…
Bulk transport through superconducting hybrid structures in HgTe quantum wells
E. G. Novik, M. Guigou, P. Recher
We investigate the subgap bulk transport through short and wide superconducting hybrid structures based on HgTe quantum wells (QWs). We show that the differential conductance of a…
Density of states of interacting quantum wires with impurities: a Dyson equation approach
R. Zamoum, M. Guigou, C. Bena +1
We calculate the density of states for an interacting quantum wire in the presence two impurities of arbitrary potential strength. To perform this calculation, we describe the Coul…
Spin-dependent thermoelectric transport in HgTe/CdTe quantum wells
D. G. Rothe, E. M. Hankiewicz, B. Trauzettel +1
We analyze thermally induced spin and charge transport in HgTe/CdTe quantum wells on the basis of the numerical non-equilibrium Green's function technique in the linear response re…
Spin Hall effect at interfaces between HgTe/CdTe quantum wells and metals
M. Guigou, P. Recher, J. Cayssol +1
We study the spin-dependent transmission through interfaces between a HgTe/CdTe quantum well (QW) and a metal - both for the normal metal and the superconducting case. Interestingl…
Andreev spectroscopy of doped HgTe quantum wells
M. Guigou, J. Cayssol
We investigate the Andreev reflection process in high-mobility HgTe/CdTe quantum wells. We find that Andreev conductance probes the dynamics of massive 2+1 Dirac fermions, and that…
Screening of a Luttinger liquid wire by a scanning tunneling microscope tip: II. Transport properties
Marine Guigou, Thierry Martin, Adeline Crépieux
We study the effect of an electrostatic coupling between a scanning tunneling microscope tip and a Luttinger liquid wire on the tunneling current and noise between the two. Solving…
Screening of a Luttinger liquid wire by a scanning tunneling microscope tip: I. Spectral properties
Marine Guigou, Thierry Martin, Adeline Crépieux
The screening effect due to a scanning tunneling microscope tip which is placed in the vicinity of an interacting quantum wire is considered. With the help of a bosonization proced…
Photo-assisted shot noise in Coulomb interacting systems
A. Crepieux, M. Guigou, A. Popoff +2
We consider the fluctuations of the electrical current (shot noise) in the presence of a voltage time-modulation. For a non-interacting metal, it is known that the derivative of th…
