Enhancement of superconductivity by polarization of magnetic impurities in disordered films
Gleb S. Seleznev, Yakov V. Fominov
Dirty superconducting films with magnetic impurities can exhibit nontrivial behavior in a magnetic field that polarizes the impurity spins. As predicted by Kharitonov and Feigelman…

Diode effect in Shapiro steps in an asymmetric SQUID with a superconducting nanobridge
Dmitrii S. Kalashnikov, Gleb S. Seleznev, Andrei Kudriashov +4
We investigate the Josephson diode effect in an asymmetric SQUID consisting of a sinusoidal Josephson junction formed by a BiTeSe flake and a superconducting Nb nanobridge…

Influence of capacitance and thermal fluctuations on the Josephson diode effect in asymmetric higher-harmonic SQUIDs
G. S. Seleznev, Ya. V. Fominov
Asymmetric two-junction SQUIDs with different current-phase relations in the two Josephson junctions, involving higher Josephson harmonics, demonstrate a flux-tunable Josephson dio…
