Anisotropic Superconductors Between Types I and II
T. T. Saraiva, A. Vagov, V. M. Axt +2
Self-duality or matching between the magnetic and condensate characteristic lengths is a fundamental property of isotropic superconductors at the critical Bogomolnyi point (B-point…
The BCS-BEC crossover induced by a shallow band: Pushing standard superconductivity types apart
S. Wolf, A. Vagov, A. A. Shanenko +3
It is well-known that the appearance of almost-empty (shallow) conduction bands in solids strongly affects their superconducting properties. In a shallow band charge carriers are d…
Shallow-band superconductors: pushing superconductivity types apart
S. Wolf, A. Vagov, A. A. Shanenko +2
Magnetic response is a fundamental property of superconducting materials, which helps to distinguish two superconductivity types: the ideally diamagnetic type I and type II, which…
Critical superconductors
A. Vagov, A. A. Shanenko, M. V. Milošević +3
Bogomolnyi critical point, originally introduced in string theories, is fundamental to superconductivity. At the critical temperature T_c it marks the sharp border between ideally…
Ginzburg-Landau theory for multiband superconductors: microscopic derivation
N. V. Orlova, A. A. Shanenko, M. V. Milošević +3
A procedure to derive the Ginzburg-Landau (GL) theory from the multiband BCS Hamiltonian is developed in a general case with an arbitrary number of bands and arbitrary interaction…
Two-band superconductors: Extended Ginzburg-Landau formalism by a systematic expansion in small deviation from the critical temperature
A. V. Vagov, A. A. Shanenko, M. V. Milošević +2
We derive the extended Ginzburg-Landau (GL) formalism for a clean s-wave two-band superconductor by employing a systematic expansion of the free-energy functional and the correspon…
