Clusters of vortices induced by thermal gradient in mesoscopic superconductors
(2021-08-06)
The structural and magnetic properties of the vortex matter in mesoscopic superconductors have been of great interest in the last decades. Recently, it has been found that vortex-vortex interaction, which is generally ...
Free expansion of attractive and repulsive Bose-Einstein condensed vortex states
(2002-03-01)
A numerical study of the time-dependent Gross-Pitaevskii equation for an axially symmetric trap to obtain insight into the free expansion of vortex states of BEC is presented. As such, the ratio of vortex-core radius to ...
Light-matter interaction induces a shadow vortex
(2016)
By sending a light beam on a homeotropic nematic liquid-crystal cell subjected to a voltage with a photosensitive wall, a stable matter vortex can be induced at the center of the beam. When the applied voltage is decreased, ...
Clusters of vortices induced by thermal gradient in mesoscopic superconductors
(Elsevier, 2021-05-26)
The structural and magnetic properties of the vortex matter in mesoscopic superconductors have been of great interest in the last decades. Recently, it has been found that vortex-vortex interaction, which is generally ...
Crossover from type i to type II regime of mesoscopic superconductors of the first group
(2020-01-01)
In the present work, we have studied the crossover between type I and type II superconductivity on mesoscopic superconducting thin films by numerically solving the 3D Ginzburg-Landau equations. We determined the dependence ...
Use of thermal gradients for control of vortex matter in mesoscopic superconductors
(2019-07-11)
Usually, the measurements of electronic and magnetic properties of superconducting samples are carried out under a constant temperature bath. On the other hand, thermal gradients induce local variation of the superconducting ...
Stable matter-wave solitons in the vortex core of a uniform condensate
(2015-08-28)
We demonstrate a stable, mobile, dipolar or nondipolar three-dimensional matter-wave soliton in the vortex core of a uniform nondipolar condensate. All intra- and inter-species contact interactions can be repulsive for a ...
Detection of discretized single-shell penetration in mesoscopic vortex matter
(IOP Publishing, 2014-08)
We investigated configurational changes in mesoscopic vortex matter with less than thousand vortices during flux penetration in freestanding 50 μm diameter disks of Bi2Sr2CaCu2O8+δ. High-resolution AC and DC local magnetometry ...
Alternate-current dynamic reorganization and nonequilibrium phase transition in driven vortex matter
(American Physical Society, 2020-02)
Externally driven glassy systems may undergo nonequilibrium phase (NEPTs). In particular, ac-driven systems display special features, such as those observed in the vortex matter of NbSe2, where oscillatory drives reorganize ...
