Freezing transition of the vortex liquid in a layered superconductor
(Elsevier Science Publishers B.V., 2001)The self-consistent theory of Singwi, Tosi, Land, and Sjolander is used to describe the liquid-solid phase in a layered superconductor in the limit of weak interplane correlation effects as would be applicable to BSCCO ... -
The ground state and vortices in a two-dimensional Bose gas confined in a harmonic trap
(Institute of Physics Publishing, 2002)We study the ground state properties of a two-dimensional Bose gas in an harmonic trap potential using the recently proposed mean-field equation that takes into account the correct dimensionality effect. In contrast to the ... -
Ground-state properties, vortices, and collective excitations in a two-dimensional Bose-Einstein condensate with gravitylike interatomic attraction
(The American Physical Society, 2008)We study the ground-state properties of a Bose-Einstein condensate with short-range repulsion and gravitylike 1/r interatomic attraction in two-dimensions (2D). Using the variational approach we obtain the ground-state ... -
Real-time imaging of vortex-antivortex annihilation in Bi 2Sr2CaCu2O8+δ single crystals by low temperature scanning hall probe microscopy
(IOP Institute of Physics Publishing, 2006)Vortices in superconductors play an important role in operating limits and applications of the superconductors. Scanning Hall probe microscopes have proven themselves to be quantitative and non-invasive tools for investigating ... -
Vortex imaging with varying temperature revealed by SHPM on Bi2Sr2CaCu2O8+y
(Elsevier B.V., 2008)Scanning Hall probe microscopy with an effective spatial resolution of ∼1 μm has been used to investigate the vortex structures in superconducting Bi2Sr2CaCu2O8+δ single crystals in the temperature range 77.3-81.3 K and ... -
Vortex lattice of a Bose-Einstein condensate as a photonic band gap material
(IOP Institute of Physics Publishing, 2009)Photonic crystal behavior of a rotating Bose-Einstein condensate with a triangular vortex lattice is reviewed and a scheme for getting much wider band gaps is proposed. It is shown that photonic band gaps can be widened ... -
Vortex lattice of a Bose-Einstein condensate in a rotating anisotropic trap
(American Physical Society, 2004)The behavior of Bose-Einstein condensates (BEC) with a vortex lattice in a rotating anisotropic trap was studied. The single-particle wave functions for a rotating anisotropy trap were found by exactly diagonalizing the ... -
Vortices in trapped boson-fermion mixtures
(Springer, 2005)We consider a trapped system of atomic boson-fermion mixture with a quantized vortex. We investigate the density profiles of bosonic and fermionic components as functions of the boson-boson and boson-fermion short-range ...
