Cavity-induced switching between localized and extended states in a non-interacting Bose-Einstein condensate
Lu Zhou, Han Pu, Keye Zhang +2
We study an ultracold atom-cavity coupling system, which had been implemented in experiment to display weak light nonlinearity [S. Gupta \textit{et al}., Phys. Rev. Lett. \textbf{9…
Quasiparticle spectrum and dynamical stability of an atomic Bose-Einstein condensate coupled to a degenerate Fermi gas
C. P. Search, H. Pu, W. Zhang +1
The quasiparticle excitations and dynamical stability of an atomic Bose-Einstein condensate coupled to a quantum degenerate Fermi gas of atoms at zero temperature is studied. The F…
Manipulating the critical temperature for the superfluid phase transition in trapped atomic Fermi gases
C. P. Search, H. Pu, W. Zhang +2
We examine the effect of the trapping potential on the critical temperature, , for the BCS transition to a superfluid state in trapped atomic gases of fermions. for an a…
Ferromagnetism in a lattice of Bose condensates
Han Pu, Weiping Zhang, Pierre Meystre
We show that an ensemble of spinor Bose-Einstein condensates confined in a one dimensional optical lattice can undergo a ferromagnetic phase transition and spontaneous magnetizatio…
Coherent acceleration of Bose-Einstein condensates
S. Potting, M. Cramer, C. H. Schwalb +2
We present a theoretical analysis of the coherent acceleration of atomic Bose-Einstein condensates. A first scheme relies on the 'conveyor belt' provided by a frequency-chirped opt…
Generation of arbitrary Dicke states in spinor Bose-Einstein condensates
S. Raghavan, H. Pu, P. Meystre +1
We demonstrate that the combination of two-body collisions and applied Rabi pulses makes it possible to prepare arbitrary Dicke (spin) states as well as maximally entangled states…
