Mass of Abrikosov vortex in high-temperature superconductor YBaCuO
Roman Tesar, Michal Sindler, Christelle Kadlec +3
Mass of Abrikosov vortices defied experimental observation for more than four decades. We demonstrate a method of its detection in high-temperature superconductors. Similarly to el…
Coexistence of phase transitions and hysteresis near BEC
M. Männel, K. Morawetz, P. Lipavský
Multiple phases occurring in a Bose gas with finite-range interaction are investigated. In the vicinity of the onset of Bose-Einstein condensation (BEC) the chemical potential and…
Effect of an electric field on the surface superconductivity
Pavel Lipavsky, Jan Kolacek, Klaus Morawetz
We discuss an effect of the electrostatic field on superconductivity near the surface. First, we use the microscopic theory of de Gennes to show that the electric field changes the…
Boundary condition for Ginzburg-Landau theory of superconducting layers
Jan Kolacek, Pavel Lipavsky, Klaus Morawetz +1
Electrostatic charging changes the critical temperature of superconducting thin layers. To understand the basic mechanism, it is possible to use the Ginzburg-Landau theory with the…
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…
Modified Josephson Relation
Jan Kolacek, Pavel Lipavsky
For type II superconductors, Josephson has shown that vortices moving with velocity v_L create an effective electric field E'=-v_L x B. By definition the effective electric field i…
Shifts of the nuclear resonance in the vortex lattice in YBaCuO
Pavel Lipavský, Jan Kolá{č}ek, Klaus Morawetz +1
The NMR and NQR spectra of Cu in the CuO plane of YBaCuO in the superconducting state are discussed in terms of the phenomenological theory of Ginzburg-Landa…
Surface charge of a flat superconducting slab in the Meissner state
Jan Kolacek, Pavel Lipavsky, Ernst Helmut Brandt
The electrostatic potential in the flat superconducting slab is evaluated in the framework of the Ginzburg-Landau theory extended by Bardeen to low temperatures. For magnetic field…
Electrostatic potential in a superconductor
Pavel Lipavsky, Jan Kolacek, Klaus Morawetz +1
The electrostatic potential in a superconductor is studied. To this end Bardeen's extension of the Ginzburg-Landau theory to low temperatures is used to derive three Ginzburg-Landa…
Bernoulli potential at a superconductor surface
Pavel Lipavsky, Jan Kolacek, Jiri J. Mares +1
The electrostatic Bernoulli potential measured at the surface of a superconductor via Kelvin capacitive coupling is shown to be independent of the pairing mechanism. This contrasts…
Electric field in stationary superconductors
Jan Kolacek, Pavel Lipavsky
It is generally accepted that vortex core is charged, what illustrates that even in stationary superconductors electric field may be present. Vortex structure and other properties…
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…
Kinetic equation consistent with the equation of state of nuclear matter
Václav Špička, Pavel Lipavský, Klaus Morawetz
A kinetic equation which combines the quasiparticle drift of Landau's equation with a dissipation governed by a nonlocal and noninstant scattering integral in the spirit of Snider'…
