Collective modes of ultracold fermionic alkaline-earth gases with SU(N) symmetry
Sayan Choudhury, Kazi R. Islam, Yanhua Hou +3
We calculate the collective modes of ultracold trapped alkaline-earth fermionic atoms, which possess an SU() symmetry of the nuclear spin degree of freedom, and a controllable $…
Hydrodynamics of Normal Atomic Gases with Spin-orbit Coupling
Yan-Hua Hou, Zhenhua Yu
Successful realization of spin-orbit coupling in atomic gases by the NIST scheme opens the prospect of studying the effects of spin-orbit coupling on many-body physics in an unprec…
Second sound and the superfluid fraction in a resonantly interacting Fermi gas
Leonid A. Sidorenkov, Meng Khoon Tey, Rudolf Grimm +3
Superfluidity is a macroscopic quantum phenomenon, which shows up below a critical temperature and leads to a peculiar behavior of matter, with frictionless flow, the formation of…
Scaling solutions of the two fluid hydrodynamic equations in a harmonically trapped gas at unitarity
Yan-Hua Hou, Lev P. Pitaevskii, Sandro Stringari
We prove that the two fluid Landau hydrodynamic equations, when applied to a gas interacting with infinite scattering length (unitary gas) in the presence of harmonic trapping, adm…
First and second sound in a highly elongated Fermi gas at unitarity
Yan-Hua Hou, Lev P. Pitaevskii, Sandro Stringari
We consider a Fermi gas at unitarity trapped by a highly elongated harmonic potential and solve the equations of two fluid hydrodynamics at finite temperature. The propagation of s…
Collective Modes in a Unitary Fermi Gas across the Superfluid Phase Transition
Meng Khoon Tey, Leonid A. Sidorenkov, Edmundo R. Sánchez Guajardo +6
We provide a joint theoretical and experimental investigation of the temperature dependence of the collective oscillations of first sound nature exhibited by a highly elongated har…
