چکیده
The dynamics of vortices in Bose-Einstein condensates dilute cold atoms can be well formulated by Gross-Pitaevskii equation. To better understand the properties vortices, a systematic method to solve nonlinear differential equation for vortex very high precision is proposed. Through two-point Pad$\acute{\text{e}}$ approximants, these solutions are presented terms simple rational functions, which used simulation dynamics. sensitive connecting parameter and truncation orders. It improved significantly with reasonable extension order functions. errors limitation approximants discussed. This investigation may shed light on exact solution

Torsion and Quantized Vortices
A propagation torsion model for quantized vortices is proposed.The model is applied to superfluids and liquid Helium II. ce2cm In a recent paper[1] it was shown following earlier works[2, 3] that the magnetic field associated with the torsion induced defects in spacetime with intrinsic spin density source could lead to line defects carrying a quantized flux with a relation satisfying
متن کاملBreathers on quantized superfluid vortices.
We consider the propagation of breathers along a quantized superfluid vortex. Using the correspondence between the local induction approximation (LIA) and the nonlinear Schrödinger equation, we identify a set of initial conditions corresponding to breather solutions of vortex motion governed by the LIA. These initial conditions, which give rise to a long-wavelength modulational instability, res...
متن کاملQuantized vortices in mixed 3He-4He drops.
Using density functional theory, we investigate the structure of mixed (3)He(N3)-(4)He(N4) droplets with an embedded impurity (Xe atom or HCN molecule) which pins a quantized vortex line. We find that the dopant+vortex+(4)He(N4) complex, which in a previous work [F. Dalfovo et al., Phys. Rev. Lett. 85, 1028 (2000)] was found to be energetically stable below a critical size N(cr), is robust agai...
متن کاملQuantized vortices in BEC and superconductors
Quantized vortices is a well-know signature of superfluidity. They have been studied extensively in superfluid Helium, type-II superconductors, Bose Einstein condensates and more recently in Fermi gas. We will discuss some mathematical analysis and numerical simulations of the quantized vortex nucleations in superconductors and Bose-Einstein condensates and discuss their connections and similar...
متن کاملQuantized Vortices in Atomic Bose-einsten Condensates
In this review, we give an overview of the experimental and theoretical advances in the physics of quantized vortices in dilute atomic-gas Bose–Einstein condensates in a trapping potential, especially focusing on experimental research activities and their theoretical interpretations. Making good use of the atom optical technique, the experiments have revealed many novel structural and dynamic p...
