Enhancement of pairing due to the presence of resonant cavities
K. Morawetz, B. Schmidt, M. Schreiber +1
A correlated fermion system is considered surrounding a finite cavity with virtual levels. The pairing properties are calculated and the influence of the cavity is demonstrated. To…
Thermopower in superconductors
Jan Kolacek, Pavel Lipavsky
The thermopower of superconductors measured via the magnetic flux in bimetallic loop is evaluated. It is shown that by a standard matching of the electrostatic potential, known as…
Bernoulli potential in type-I and weak type-II supercoductors: II. Surface dipole
P. Lipavsky, K. Morawetz, J. Kolacek +3
The Budd-Vannimenus theorem is modified to apply to superconductors in the Meissner state. The obtained identity links the surface value of the electrostatic potential to the densi…
Bernoulli potential in type-I and weak type-II superconductors: I. Surface charge
P. Lipavsky, K. Morawetz, J. Kolacek +3
The electrostatic potential close to the surface of superconductors in the Meissner state is discussed. We show that beside the Bernoulli potential, the quasiparticle screening, an…
Electric field in type II superconductors
J. Kolacek, P. Lipavsky, V. Spicka
Generally it is accepted that electric field E in type II superconductors is created by the vortex motion, so that it is proportional to the vortex velocity v_L. This assertion is…
