Current Flow in Topological Insulator Josephson Junctions due to Imperfections
Kiryl Piasotski, Omri Lesser, Adrian Reich +5
Recent experiments on planar superconductor-topological insulator-superconductor (S-TI-S) junctions, e.g., in Corbino geometry, have reported low-temperature nonzero Josephson curr…
Density of scattering resonances in a disordered system
M. S. Kurilov, P. M. Ostrovsky
Reflection of particles from a disordered or chaotic medium is characterized by a scattering matrix that can be represented as a superposition of resonances. Each resonance corresp…
Effect of superconductivity on non-uniform magnetization in dirty SF junctions
A. V. Levin, P. M. Ostrovsky
We study proximity effect in a tunnel junction between a bulk superconductor and a thin disordered ferromagnetic layer on its surface. Cooper pairs penetrating from the superconduc…
Josephson effect in strongly disordered metallic wires
Mustafa E. Ismagambetov, Aleksey V. Lunkin, Pavel M. Ostrovsky
We study localization effects in Josephson junctions with two superconductors connected by a strongly disordered metallic wire of length . The conventional description of the Jo…
