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...
Magnetic Field Delocalization and Flux Inversion in Fractional Vortices in Two-Component Superconductors
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...
Counting Majorana zero modes in superconductors
Counting Majorana zero modes superconductors
2010/12/24
A counting formula for computing the number of (Majorana) zero modes bound to topological point defects is evaluated in a gradient expansion for systems with charge-conjugation symmetry. This semi-cl...
Holographic superconductors in the Born-Infeld electrodynamics
Holographic superconductors Born-Infeld electrodynamics
2010/3/18
We study the effects of the Born-Infeld electrodynamics on the holographic superconductors in the background of a Schwarzschild AdS black hole spacetime. We find that the presence of Born-Infeld scale...
