Impurity-induced Inverse Faraday Effect
A. A. Kopasov, A. A. Bespalov, A. S. Mel'nikov
We provide a quantum-mechanical description of the photoinduced dc current states and magnetic fields around nonmagnetic point impurities in a two-dimensional (2D) electron gas irr…
Large spectral gap and impurity-induced states in a two-dimensional Abrikosov vortex
A. A. Bespalov, V. D. Plastovets
We study the subgap spectrum of a 2D Abrikosov vortex in an s-wave superconductor in the absence and presence of a point impurity. By solving the Eilenberger equations without impu…
Impurity-induced subgap states in superconductors with inhomogeneous pairing
A. A. Bespalov
We study subgap states induced by a single impurity in an s-wave superconductor with suppressed pairing. For concreteness, we consider a bulk superconductor containing a normal sph…
How many quasiparticles can be in a superconductor?
Anton Bespalov, Manuel Houzet, Julia S. Meyer +1
Experimentally and mysteriously, the concentration of quasiparticles in a gapped superconductor at low temperatures always by far exceeds its equilibrium value. We study the dynami…
Density of states in gapped superconductors with pairing-potential impurities
Anton Bespalov, Manuel Houzet, Julia S. Meyer +1
We study the density of states in disordered s-wave superconductors with a small gap anisotropy. Disorder comes in the form of common nonmagnetic scatterers and pairing-potential i…
Magnon radiation by moving Abrikosov vortices in ferromagnetic superconductors and superconductor-ferromagnet multilayers
A. A. Bespalov, A. S. Mel'nikov, A. I. Buzdin
In systems combining type-II superconductivity and magnetism the non-stationary magnetic field of moving Abrikosov vortices may excite spin waves, or magnons. This effect leads to…
Pinning of an Abrikosov vortex on a small cylindrical cavity: A Ginzburg-Landau approach
A. A. Bespalov, A. S. Mel'nikov
Within the Ginzburg-Landau theory we consider Abrikosov vortex pinning on a columnar defect with the characteristic size of the cross-section much smaller than the coherence length…
Mismatch of conductivity anisotropy in the mixed and normal states of type-II superconductors
A. A. Bespalov, A. S. Mel'nikov
We have calculated the Bardeen-Stephen contribution to the vortex viscosity for uniaxial anisotropic superconductors within the time-dependent Ginzburg-Landau (TDGL) theory. We foc…
