Critical Current Oscillations versus Pureness of Superconductor-ferromagnet Nanoscopic Multilayers

Shafranjuk S.E., Ketterson J., Northwestern University, US

In our report we study how the oscillations and reentrant behaviour of critical parameters depends on the elastic scattering of electrons on atomic impurities in S/F multilayers. The expressions for the electric supercurrent and for [...]

Switching Dynamics of Double Barrier Josephson Junction Based Qubit Gate

Shafraniuk S.E., Nevirkovets I.P., Ketterson J., Northwestern University, US

The double barrier SINIS junctions (here S, I, and N denote a superconductor, an insulator, and a normal metal, respectively) with a nanoscopic N spacer are potentially capable of performing quantum logic operations (so-called qubits) [...]
