Effect of magnetic pair breaking on Andreev bound states and resonant supercurrent in quantum dot Josephson junctions
Grygoriy Tkachov, Klaus Richter
We propose a model for resonant Josephson tunneling through quantum dots that accounts for Cooper pair-breaking processes in the superconducting leads caused by a magnetic field or…
Andreev magnetotransport in low-dimensional proximity structures: Spin-dependent conductance enhancement
Grygoriy Tkachov, Klaus Richter
We study the excess conductance due to the superconducting proximity effect in a ballistic two-dimensional electron system subject to an in-plane magnetic field. We show that under…
Nonmetallic thermal transport in low-dimensional proximity structures with partially preserved time-reversal symmetry in a magnetic field
G. Tkachov
Gapped excitation spectra of Andreev states are studied in one- and two-dimensional (1D and 2D) normal systems in superconducting contacts subject to a parallel magnetic field. In…
Nonmonotonic inelastic tunneling spectra due to surface spin excitations in ferromagnetic junctions
G. Tkachov
The paper addresses inelastic spin-flip tunneling accompanied by surface spin excitations (magnons) in ferromagnetic junctions. The inelastic tunneling current is proportional to t…
Magnetic field influence on the proximity effect in semiconductor - superconductor hybrid structures and their thermal conductance
Grygoriy Tkachov, Vladimir I. Fal'ko
We show that a magnetic field can influnce the proximity effect in NS junctions via diamagnetic screening current flowing in the superconductor. Using ballistic quasi-one-dimension…
Subgap transport in ferromagnet-superconductor junctions due to magnon-assisted Andreev reflection
Grygoriy Tkachov, Edward McCann, Vladimir I. Fal'ko
We propose a new process of magnon-assisted Andreev reflection at a ferromagnetic metal - superconductor interface, which consists of the simultaneous injection of a Cooper pair fr…
