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...
Dark-bright solitons and vortices in Bose-Einstein condensates
Bose-Einstein condensates dark-bright soliton Gross Pitaevskii equations
2014/12/8
This dissertation focuses on the properties of nonlinear waves in Bose-Einstein condensates (BECs). The fundamental model here is the nonlinear Schrodinger equation, the so-called Gross-Pitaevskii (GP...

Vortices chirality multi-band superconductors
2012/2/27
We investigate several important properties of multi-band superconductors. They are time-reversal symmetry breaking, chirality and fractional quantum flux vortices in three-band superconductors. The B...
Rotating superfluids in anharmonic traps: From vortex lattices to giant vortices
anharmonic traps vortex lattices giant vortices Quantum Gases
2011/10/9
Abstract: We study a superfluid in a rotating anharmonic trap and explicate a rigorous proof of a transition from a vortex lattice to a giant vortex state as the rotation is increased beyond a limitin...

2011/7/28
Abstract: Electrodynamic phenomena related to vortices in superconductors have been studied since their prediction by Abrikosov, and seem to hold no fundamental mysteries. However, most of the effects...

2013/7/3
The properties of a pair of vortices embedded in a Gaussian beam focused by a high numerical-aperture are studied on the basis of vector Debye integral. The vortices move and rotate in the vicinity of...

Generation and Dynamics of Quantized Vortices in a Unitary Fermi Superfluid
Generation Dynamics of Quantized Vortices Unitary Fermi Superfluid
2011/1/10
Superfluidity and superconductivity are remarkable manifestations of quantum coherence at a macroscopic scale. The dynamics of superfluids has dominated the study of these systems for decades now, but...
Five-minutes oscillations is one of the basic properties of solar convection. Observations show mixture of a large number of acoustic wave fronts propagating from their sources. We investigate the pr...
Scattering on two Aharonov-Bohm vortices with opposite fluxes
Aharonov-Bohm vortices opposite fluxes
2010/4/2
The scattering of an incident plane wave on two Aharonov-Bohm vortices with opposite fluxes is considered in detail. The presence of the vortices imposes non-trivial boundary conditions for the partia...
