Spatial Landau-Zener-Stückelberg interference in spinor Bose-Einstein condensates
Spatial spinor Bose-Einstein condensates
2010/11/24
We investigate the St¨uckelberg oscillations of a spin-1 Bose-Einstein condensate subject to a
spatially inhomogeneous transverse magnetic field and a periodic longitudinal field. We show that the ti...
Finite-Temperature Density-Functional Theory of Bose-Einstein Condensates
Finite-Temperature Density-Functional Theory Bose-Einstein Condensates
2010/11/25
The thermodynamic approach to density functional theory (DFT) is used to derive a versatile
theoretical framework for the treatment of finite–temperature (and in the limit, zero temperature)Bose–Eins...
Spontaneously axisymmetry breaking phase in a binary mixture of spinor Bose-Einstein condensates
Spontaneously axisymmetry spinor Bose-Einstein condensates
2010/11/17
We study the ground state phases for a mixture of two atomic spin-1 Bose-Einstein condensates
(BECs) in the presence of a weak magnetic (B-) field. The ground state is found to contain a
broken-axis...
Dynamical generation of phase-squeezed states in a two-component Bose-Einstein condensates
Dynamical generation of phase-squeezed states two-component Bose-Einstein condensates
2010/11/22
As an “input” state of a linear (Mach-Zehnder or Ramsey) interferometer, the phase-squeezed
state proposed by Berry and Wiseman exhibits the best sensitivity approaching to the Heisenberg
limit [Phy...
Phase diffusion of a two-component Bose-Einstein condensates: exact and short-time solutions for arbitrary coherent spin state
two-component Bose-Einstein condensates arbitrary coherent spin state
2010/11/23
We investigate phase diffusion of a two-component Bose-Einstein condensates prepared initially in arbitrary coherent spin state |θ0, φ0i. Analytical expression of the phase-diffusion time is presented...
