Quantum Fluctuations in the Superfluid State of the BCS-BEC Crossover
Roberto B. Diener, Rajdeep Sensarma, Mohit Randeria
We determine the effects of quantum fluctuations about the T=0 mean field solution of the BCS-BEC crossover in a dilute Fermi gas using the functional integral method. These fluctu…
Criterion for bosonic superfluidity in an optical lattice
Roberto B. Diener, Qi Zhou, Hui Zhai +1
We show that the current method of determining superfluidity in optical lattices based on a visibly sharp bosonic momentum distribution can be misleading, for even a n…
Quantum Spin Dynamics of Spin-1 Bose Gas
Roberto B. Diener, Tin-Lun Ho
We show that the quantum evolution of a spin-1 Bose gas with nearly all bosons initially in the state has a "quantum carpet" {\em spin-time} structure with self-similar p…
Cr Spinor Condensate A Biaxial or Uniaxial Spin Nematic
Roberto B. Diener, Tin-Lun Ho
We show that the newly discovered Cr Bose condensate in zero magnetic field can be a spin nematic of the following kind: A "maximum" polar state, a "co-linear" polar state,…
Fermions in Optical Lattices across Feshbach Resonance
Roberto B. Diener, Tin-Lun Ho
We point out that the recent experiments at ETH \cite{Esslinger} on fermions in optical lattices, where a band insulator evolves continuously into states occupying many bands as th…
Fermion Superfluids of Non-Zero Orbital Angular Momentum near Resonance
Tin-Lun Ho, Roberto B. Diener
We study the pairing of Fermi gases near the scattering resonance of the partial wave. Using a model potential which reproduces the actual two-body low energy scatteri…
