Classical phases and quantum angles in the description of interfering Bose-Einstein condensates
Condensate random variables measurements
2014/12/19
The interference of two Bose-Einstein condensates, initially in Fock states, can be described in terms of their relative phase, treated as a random unknown variable. This phase can be understood eithe...
Beyond Spontaneously Broken Symmetry in Bose-Einstein Condensates
Condensate treatment stage bell inequality particles quantum Angle the population oscillation
2014/12/19
Spontaneous symmetry breaking (SSB) for Bose-Einstein condensates cannot treat phase off-diagonal effects, and thus cannot explain Bell inequality violations. We describe another situation that is bey...
Many physicists believed it could not be done, but now a team in Germany has created a Bose–Einstein condensate (BEC) from photons. BECs are formed when identical bosons – particles with integer spin ...
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 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...
Phase transition to Bose-Einstein condensation for a Bosonic gas confined in a combined trap
Bose-Einstein condensation Bosonic gas confined
2010/11/22
We present a study of phase transition to macroscopic superfluidity for an ultracold bosonic gas confined in a combined trap formed by a one-dimensional optical lattice and a harmonic potential,focusi...
Anisotropic superfluidity in a dipolar Bose gas
Anisotropic superfluidity dipolar Bose gas
2010/11/22
We study the superfluid character of a dipolar Bose-Einstein condensate (DBEC) in a quasi-two
dimensional (q2D) geometry. In particular, we allow for the dipole polarization to have some non-zero pro...
Relevance of Bose-Einstein Condensation to the Interference of Two Independent Bose Gases
Bose-Einstein Condensation Two Independent Bose Gases
2010/11/18
Interference of two independently prepared ideal Bose gases is discussed, on the basis of the idea of measurement-induced interference: even if the number of each gas is individually fixed finite and ...
Fast production of large 23Na Bose-Einstein condensates in an optically plugged magnetic quadrupole trap
optically plugged magnetic quadrupole trap
2010/11/18
We demonstrate a fast production of large 23Na Bose-Einstein condensates in an optically plugged,magnetic quadrupole trap. A single global minimum of the trapping potential is generated by slightly di...
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...

In his Comment [see preceding Comment, Phys. Rev. A 82, 037601 (2010)] on the paper by Roux [Phys.Rev. A 79, 021608(R) (2009)], Rigol argued that the energy distribution after a quench is not related ...

2010/11/18
Recently, Freilich et al. [Science 329, 1182 (2010)] experimentally discovered stationary states of vortex dipoles, pairs of vortices of opposite circulation, in dilute Bose–Einstein condensates.To ex...
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...

We study the formation of a Bose-Einstein condensate in a cigar-shaped three-dimensional harmonic trap,induced by the controlled addition of an attractive “dimple” potential along the weak axis. In th...
