A novel method to create a vortex in a Bose-Einstein condensate
, 2002 It has been shown that a vortex in a BEC with spin degrees of freedom can be created by manipulating with external magnetic fields. In the previous work, an optical plug along the vortex axis has been introduced to avoid Majorana flips, which take place ...

Bose-Fermi Mixtures in Optical Lattices [PDF]
, 2005 Using mean field theory, we have studied Bose-Fermi mixtures in a one-dimensional optical lattice in the case of an attractive boson-fermion interaction.

Acoustic superradiance from an optical-superradiance-induced vortex in a Bose-Einstein condensate
, 2014 We consider the simultaneous scattering of an angular momentum carrying Laguerre-Gaussian light beam and an acoustic wave from an atomic Bose-Einstein condensate, under condition of optical superradiance induced vortex state.

Reconstructing the Poynting vector skew angle and wave-front of optical vortex beams via two-channel moir\'e deflectometery [PDF]
, 2013 A novel approach based on the two-channel moir\'e deflectometry has been used to measure both wave-front and transverse component of the Poynting vector of an optical vortex beam. Generated vortex beam by the q-plate, an inhomogeneous liquid crystal cell,

Integrated Compact Optical Vortex Beam Emitters [PDF]
Science, 2012 A Twist of Light The angular momentum of photons can be used to encode and transmit information. Cai et al. (p. 363 ) developed a method for generating and emitting controllable orbital angular momentum states of light from a reconfigurable ...

Giant Colloidal Diffusivity on Corrugated Optical Vortices
, 2006 A single colloidal sphere circulating around a periodically modulated optical vortex trap can enter a dynamical state in which it intermittently alternates between freely running around the ring-like optical vortex and becoming trapped in local potential
