Bogoliubov modes of a dipolar condensate in a cylindrical trap

S Ronen, DCE Bortolotti, JL Bohn - … Review A—Atomic, Molecular, and Optical …, 2006 - APS
The calculation of properties of Bose-Einstein condensates with dipolar interactions has
proven a computationally intensive problem due to the long range nature of the interactions …

Unitary fermi supersolid: The larkin-ovchinnikov phase

A Bulgac, MMN Forbes - Physical review letters, 2008 - APS
We present strong theoretical evidence that a Larkin-Ovchinnikov (LOFF/FFLO) pairing
phase is favored over the homogeneous superfluid and normal phases in three-dimensional …

Collisionless dynamics of dilute Bose gases: Role of quantum and thermal fluctuations

S Giorgini - Physical Review A, 2000 - APS
We study the low-energy collective oscillations of a dilute Bose gas at finite temperature in
the collisionless regime. By using a time-dependent mean-field scheme we derive for the …

Fulde-Ferrell-Larkin-Ovchinnikov states in one-dimensional spin-polarized ultracold atomic Fermi gases

XJ Liu, H Hu, PD Drummond - Physical Review A—Atomic, Molecular, and …, 2007 - APS
We present a systematic study of quantum phases in a one-dimensional spin-polarized
Fermi gas. Three comparative theoretical methods are used to explore the phase diagram at …

Number-conserving approach to a minimal self-consistent treatment of condensate and noncondensate dynamics in a degenerate Bose gas

SA Gardiner, SA Morgan - Physical Review A—Atomic, Molecular, and Optical …, 2007 - APS
We describe a number-conserving approach to the dynamics of Bose-Einstein condensed
dilute atomic gases. This builds upon the works of Gardiner [Phys. Rev. A 56, 1414 (1997)] …

Finite-temperature phase diagram of a spin-polarized ultracold Fermi gas in a highly elongated harmonic trap

XJ Liu, H Hu, PD Drummond - Physical Review A—Atomic, Molecular, and …, 2008 - APS
We investigate the finite-temperature properties of an ultracold atomic Fermi gas with spin
population imbalance in a highly elongated harmonic trap. Previous studies at zero …

Quasiparticle continuum and resonances in the Hartree-Fock-Bogoliubov theory

JC Pei, AT Kruppa, W Nazarewicz - Physical Review C—Nuclear Physics, 2011 - APS
The quasiparticle energy spectrum of the Hartree-Fock-Bogoliubov (HFB) equations
contains discrete bound states, resonances, and nonresonant continuum states. We study …

Finite-temperature analysis of a quasi-two-dimensional dipolar gas

C Ticknor - Physical Review A—Atomic, Molecular, and Optical …, 2012 - APS
We present a finite-temperature analysis of a quasi-two-dimensional (Q2D) dipolar gas. To
do this, we use the Hartree-Fock-Bogoliubov method within the Popov approximation. This …

Mean-field thermodynamics of a spin-polarized spherically trapped Fermi gas at unitarity

XJ Liu, H Hu, PD Drummond - Physical Review A—Atomic, Molecular, and …, 2007 - APS
We calculate the mean-field thermodynamics of a spherically trapped Fermi gas with
unequal spin populations in the unitarity limit, comparing results from the Bogoliubov–de …

Response of Bose-Einstein condensates to external perturbations at finite temperature

SA Morgan - Physical Review A, 2004 - APS
We present a theory of the linear response of a Bose-Einstein-condensed gas to external
perturbations at finite temperature. The theory developed here is the basis of a recent …
