Comparison of multiple flux quantum transition with the corresponding I-U-characteristic using Nb-point contacts

چکیده
2014 For Superconductor-Superconductor (S-S) point contacts (Nb) a quantitative check is done whether the properties of flux quantum transition into a weakly connected superconducting loop can be predicted from the shape of the corresponding I-U-characteristic. The background is taken from the Resistively Shunted Junction (RSJ)-model using a modified sinusoidal Current-Phase-Relation (CPR). An experimental set-up was built to measure the I-U-characteristic and the flux penetration at the same point contact. The quantitative agreement between the predictions of the RSJ-model and the results of the experiment is surprisingly good. Revue Phys.

Direct demonstration of circulating currents in a controllable p-SQUID generated by a 0 to p transition of the weak links
A controllable p-SQUID is a DC SQUID ~direct-current superconducting quantum interference device! with two controllable p junctions as weak links. A controllable p junction consists of a superconducting–normal metal–superconducting Josephson junction with two additional contacts to the normal region of the junction. By applying a voltage Vc over these contacts it is possible to control the stat...
متن کاملA note on magnetic-field induced level-density condensation in a two-dimensional electron gas with point scatterers
The density-of-states (DOS) for a magnetized (B) two-dimensional electron gas (2DEG) containing point scatterers of arbitrary strengths, concentration (ns) and distribution is analyzed. It is shown from the first principles that for ns ≤ B/Φo ≡ nB, the areal density of flux quanta Φo ≡ hc/e, the DOS retains the extensive degeneracy characteristic of the Landau levels, but reduced by a factor (1...

Abstract We consider relativistic U(1) gauge theories in 2 + 1 dimensions, with Nb species of complex bosons and Nf species of Dirac fermions at finite temperature. The quantum phase transition between the Higgs and Coulomb phases is described by a conformal field theory (CFT). At large Nb and Nf , but for arbitrary values of the ratio Nb/Nf , we present computations of various critical exponen...
متن کاملOrigin of the matching effect in a superconducting film with a hole array
We investigate the origin of the matching effect observed in superconducting Nb films containing regular arrays of holes near the zero-field critical temperature. We find “dips” in the resistance vs magnetic field curves at matching fields where the magnitude of the magnetic flux threading each unit cell is an integer number of the flux quantum. By comparing the magnetic field dependences of th...
