Phase Coherence in a Driven Double-Well System
T. Miyakawa, C. P. Search, P. Meystre
We analyze the dynamics of the molecular field incoherently pumped by the photoassociation of fermionic atoms and coupled by quantum tunnelling in a double-well potential. The rela…
Wave mixing of optical pulses and Bose-Einstein condensates
Han Pu, Weiping Zhang, Pierre Meystre
We investigate theoretically the four-wave mixing of optical and matter waves resulting from the scattering of a short light pulse off an atomic Bose-Einstein condensate, as recent…
Effective mass analysis of Bose-Einstein condensates in optical lattices -- stabilization and levitation
H. Pu, L. O. Baksmaty, W. Zhang +2
We investigate the time evolution of a Bose-Einstein condensate in a periodic optical potential. Using an effective mass formalism, we study the equation of motion for the envelope…
Macroscopic spin tunneling and quantum critical behavior of a condensate in double-well potential
Han Pu, Weiping Zhang, Pierre Meystre
In a previous work (PRL 87, 140405), we have shown that a spinor condensate confined in a periodic or double-well potential exhibits ferromagnetic behavior due to the magnetic dipo…
Raman coupler for a trapped two-component quantum-degenerate Fermi gas
S. Potting, M. Cramer, W. Zhang +1
We investigate theoretically the Raman coupling between two internal states of a trapped low-density quantum-degenerate Fermi gas. In general, the trap frequencies associated with…
Diffraction of a superfluid Fermi gas by an atomic grating
C. P. Search, H. Pu, W. Zhang +1
An atomic grating generated by a pulsed standing wave laser field is proposed to manipulate the superfluid state in a quantum degenerate gas of fermionic atoms. We show that in the…
