Temperature of a trapped unitary Fermi gas at finite entropy
Hui Hu, Xia-Ji Liu, Peter D. Drummond
We present theoretical predictions for the equation of state of a harmonically-trapped Fermi gas in the unitary limit. Our calculations rest on a study of the equation of state of…
Equation of state of a superfluid Fermi gas in the BCS-BEC crossover
Hui Hu, Xia-Ji Liu, Peter D. Drummond
We present a theory for a superfluid Fermi gas near the BCS-BEC crossover, including pairing fluctuation contributions to the free energy similar to that considered by Nozieres and…
Signature of Mott-insulator transition with ultra-cold fermions in a one-dimensional optical lattice
Xia-Ji Liu, Peter D. Drummond, Hui Hu
Using the exact Bethe ansatz solution of the Hubbard model and Luttinger liquid theory, we investigate the density profiles and collective modes of one-dimensional ultra-cold fermi…
Gauge Poisson representations for birth/death master equations
P. D. Drummond
Poisson representation techniques provide a powerful method for mapping master equations for birth/death processes -- found in many fields of physics, chemistry and biology -- into…
Limits to squeezing in the degenerate OPO
S. Chaturvedi, K. Dechoum, P. D. Drummond
We develop a systematic theory of quantum fluctuations in the driven parametric oscillator (OPO), including the region near threshold. This allows us to treat the limits imposed by…
How to mode-lock an atom laser
Peter D. Drummond, Antonios Eleftheriou, Kerson Huang +1
We consider a possible technique for mode-locking an atom laser, based on the generation of a dark soliton in a ring-shaped Bose-Einstein condensate, with repulsive atomic interact…
