Anisotropic time-dependent London approach
V. G. Kogan, R. Prozorov
The anisotropic London equations taking into account the normal currents are derived and applied to the problem of the surface impedance in the Meisner state of anisotropic materia…
Locking of length scales in two-band superconductors
M. Ichioka, V. G. Kogan, J. Schmalian
A model of a clean two-band s-wave superconductor with cylindrical Fermi surfaces, different Fermi velocities v_{1,2}, and a general 2x2 coupling matrix V_{alpha beta} is used to s…
Vortices in normal part of proximity system
V. G. Kogan
It is shown that the order parameter induced in the normal part of superconductor-normal-superconductor proximity system is modulated in the magnetic field differently from vor…
Changing the type of superconductivity by magnetic and potential scattering
V. G. Kogan, R. Prozorov
By evaluating the upper and thermodynamic critical fields, and , and their ratio at arbitrary temperatures, we argue that situations are possible when a…
Effect of current injection into thin-film Josephson junctions
V. G. Kogan, R. G. Mints
New thin-film Josephson junctions have recently been tested in which the current injected into one of the junction banks governs Josephson phenomena. One thus can continuously mana…
Anisotropic criteria for the type of superconductivity
V. G. Kogan, R. Prozorov
The classical criterion for classification of superconductors as type-I or type-II based on the isotropic Ginzburg-Landau theory is generalized to arbitrary temperatures for materi…
