Domain wall effects in ferromagnet-superconductor structures
I. S. Burmistrov, N. M. Chtchelkatchev
We investigate how domain structure of the ferromagnet in superconductor-ferromagnet heterostructures may change their transport properties. We calculate the distribution of curren…
Andreev conductance of a domain wall
Nikolai M. Chtchelkatchev, Igor S. Burmistrov
At low temperatures, the transport through a superconductor-ferromagnet tunnel interface is due to tunneling of electrons in pairs. Exchange field of a monodomain ferromagnet align…
Noise correlations, entanglement, and Bell inequalities
T. Martin, A. Crepieux, N. Chtchelkatchev
The aim of this chapter is to describe two situations where positive noise correlations can be directly monitored using a transport experiment, either with a superconductor or with…
Nonmonotonic critical temperature in superconductor/ferromagnet bilayers
Ya. V. Fominov, N. M. Chtchelkatchev, A. A. Golubov
The critical temperature T_c of a superconductor/ferromagnet (SF) bilayer can exhibit nonmonotonic dependence on the thickness d_f of the F layer. SF systems have been studied for…
Supercurrent Quantization in Narrow Channel SNS Junctions
Nikolai M. Chtchelkatchev, Gordey B. Lesovik, Gianni Blatter
We determine the quasi-particle excitation spectrum in the normal region of a narrow ballistic superconductor--normal-metal--superconductor (SNS) Josephson contact. Increasing the…
