Superconductors – metals in which electricity flows without resistance – hold promise as the defining material of the near future, according to physicist Brad Ramshaw, and are already used in medical ...
Wakanda, the mythical setting for Marvels’ superhero film “Black Panther,” is home to some not-so-mythical technology. An indestructible cape might not yet be possible, but Wakanda’s levitating high-s...
Spin bath-mediated decoherence in superconductors
Squid tunnel paramagnetic nuclear spin electronic excited state isotope purification
2014/12/22
We consider a SQUID tunneling between 2 nearly degenerate flux states. Decoherence caused by paramagnetic and nuclear spins in the low-T limit is shown to be much stronger than that from electronic ex...

One-component Abrikosov vortex superconductors vortex vortex
2014/12/19
We demonstrate that, in contrast with the single-component Abrikosov vortex, in two-component superconductors vortex solutions with an exponentially screened magnetic field exist only in exceptional c...

2014/12/18
We show that in multiband superconductors, even an extremely small interband proximity effect can lead to a qualitative change in the interaction potential between superconducting vortices by producin...

2012/4/19
Predicting the transition temperature, Tc, of a superconductor from Periodic Table normal state properties is regarded as one of the grand challenges of superconductivity. By studying the correlations...

We consider the effect of nonmagnetic and magnetic impurities on the superheating field $H_s$ in a type-II superconductor. We solved the Eilenberger equations, which take into account the nonlinear pa...

2012/2/27
A quarter of a century after their discovery the mechanism that pairs carriers in the cuprate high-Tc superconductors (HTS) still remains uncertain. Despite this the general consensus is that it is pr...
Quantum-fluctuation effects in transport properties of superconductors above the paramagnetic limit
Quantum-fluctuation effects transport properties superconductors the paramagnetic limit
2012/2/27
We study the transport in ultrathin disordered film near the quantum critical point induced by the Zeeman field. We calculate corrections to the normal state conductivity due to quantum pairing fluctu...
We present a study of the possible plasmon excitations that can occur in systems where strong superconductivity is present. In these systems the plasmon energy is comparable to, or smaller than the pa...
