Stationary arrays of vortices in Bose-Einstein condensates confined by a toroidal trap
(IOP Publishing, 2009)
Metastable off-axis vortices in nonrotating Bose-Einstein condensates
(IOP Publishing, 2008-02)
We propose a scenario for studying vortices confined by nonrotating traps. For this purpose we model a polynomial trapping potential that can sustain locally stable off-axis vortices. We also describe a simple numerical ...
A Vortical Dawn Flank Boundary Layer for Near-Radial IMF: Wind Observations on October 24, 2001
(American Geophysical Union, 2014-06)
We present an example of a boundary layer tailward of the dawn terminator which is entirely populated by rolled-up flow vortices. Observations were made by Wind on October 24, 2001 as the spacecraft moved across the region ...
Determining the fractional topological charge shifting in perfect vortices from laser speckle
(Elsevier Science, 2019-06-15)
We demonstrate analytically, numerically, and experimentally that the fractional topological charge shifting in perfect vortices having a ring-shaped distribution is precisely determined by the correlation coefficient of ...
Vortices in fracton type gauge theories
(Elsevier Science, 2020-12)
We consider a vector gauge theory in 2+1 dimensions of the type recently proposed by Radzihovsky and Hermele [1] to describe fracton phases of matter. The theory has U(1)×U(1) vector gauge fields coupled to an additional ...
Magnetic structures and Z2 vortices in a non-Abelian gauge model
(American Physical Society, 2015-12)
The magnetic order of the triangular lattice with antiferromagnetic interactions is described by an SO(3) field and allows for the presence of Z2 magnetic vortices as defects. In this work we show how these Z2 vortices can ...
Effects of the induced birefringence in photorefractive crystals on speckle optical vortices
(Elsevier, 2012-03)
In this work, we show that it is possible to change the properties of an optical vortex formed in a speckle pattern by the control of an external electric field applied to a sillenite-type photorefractive material in a ...
Reexamination of Bessel beams: A generalized scheme to derive optical vortices
(American Physical Society, 2019-02)
The electromagnetic field of optical vortices is in most cases derived from vector and scalar potentials using either a procedure based on the Lorenz or the Coulomb gauge. The former procedure has been typically used to ...
Structure of vortices in two-component Bose-Einstein condensates
(American Physical Society, 2001-07)
We develop a three-dimensional analysis of the phase separation of two-species Bose-Einstein condensates in the presence of vorticity within the Thomas-Fermi approximation. We find different segregation features according ...
Vortices in Bose-Einstein condensates with dominant dipolar interactions
(American Physical Society, 2009-06)
We present full three-dimensional numerical calculations of single vortex states in rotating dipolar condensates. We consider a Bose-Einstein condensate of C 52 r atoms with dipole-dipole and s -wave contact interactions ...
