Interferometric evidence of non-volatile anomalous phase shifts in exchange-spin-split Josephson supercurrent diodes
Kun-Rok Jeon, Jae-Keun Kim, Jiho Yoon +5
The recent realization of zero-field, polarity-reversible supercurrent rectification in proximity-magnetized Rashba-type Pt Josephson junctions (JJs) enables the development of sup…
General Boundary Conditions for Quasiclassical Theory of Superconductivity in the Diffusive Limit: Application to Strongly Spin-polarized Systems
M. Eschrig, A. Cottet, W. Belzig +1
Boundary conditions in quasiclassical theory of superconductivity are of crucial importance for describing proximity effects in heterostructures between different materials. Althou…
Inducing odd-frequency triplet superconducting correlations in a normal metal
Audrey Cottet
This work discusses theoretically the interplay between the superconducting and ferromagnetic proximity effects, in a diffusive normal metal strip in contact with a superconductor…
Spin-dependent boundary conditions for isotropic superconducting Green's functions
Audrey Cottet, Daniel Huertas-Hernando, Wolfgang Belzig +1
The quasiclassical theory of superconductivity provides the most successful description of diffusive heterostructures comprising superconducting elements, namely, the Usadel equati…
Superconducting/ferromagnetic diffusive bilayer with a spin-active interface: a numerical study
Audrey Cottet, Jacob Linder
We calculate the density of states (DOS) in a diffusive superconducting/ferromagnetic bilayer with a spin-active interface. We use a self-consistent numerical treatment to make a s…
Conductance and current noise of a superconductor/ferromagnet quantum point contact
Audrey Cottet, Wolfgang Belzig
We study the conductance and current noise of a superconductor/ferromagnet (S/F) single channel Quantum Point Contact (QPC) as a function of the QPC bias voltage, using a scatterin…
Spectroscopy and critical temperature of diffusive superconducting/ferromagnetic hybrid structures with spin-active interfaces
Audrey Cottet
The description of the proximity effect in superconducting/ferromagnetic heterostructures requires to use spin-dependent boundary conditions. Such boundary conditions must take int…
Superconducting proximity effect in a diffusive ferromagnet with spin-active interfaces
Audrey Cottet, Wolfgang Belzig
We reconsider the problem of the superconducting proximity effect in a diffusive ferromagnet bounded by tunneling interfaces, using spin-dependent boundary conditions. This introdu…
