Quantized superfluid vortex rings in the unitary Fermi gas.
In a recent article, Yefsah et al. [Nature (London) 499, 426 (2013)] report the observation of an unusual excitation in an elongated harmonically trapped unitary Fermi gas. After phase imprinting a domain wall, they observe oscillations almost an order of magnitude slower than predicted by any theory of domain walls which they interpret as a "heavy soliton" of inertial mass some 200 times large...
متن کاملVortex shedding and drag in dilute Bose-Einstein condensates
Above a critical velocity, the dominant mechanism of energy transfer between a moving object and a dilute Bose-Einstein condensate is vortex formation. In this paper, we discuss the critical velocity for vortex formation and the link between vortex shedding and drag in both homogeneous and inhomogeneous condensates. We find that at supersonic velocities sound radiation also contributes signific...
متن کاملCritical superfluid velocity in a trapped dipolar gas.
We investigate the superfluid properties of a dipolar Bose-Einstein condensate (BEC) in a fully three-dimensional trap. Specifically, we estimate a superfluid critical velocity for this system by applying the Landau criterion to its discrete quasiparticle spectrum. We test this critical velocity by direct numerical simulation of condensate depletion as a blue-detuned laser moves through the con...
متن کاملDrag force on an impurity below the superfluid critical velocity in a quasi-one-dimensional Bose-Einstein condensate.
The existence of frictionless flow below a critical velocity for obstacles moving in a superfluid is well established in the context of the mean-field Gross-Pitaevskii theory. We calculate the next order correction due to quantum and thermal fluctuations and find a nonzero force acting on a delta-function impurity moving through a quasi-one-dimensional Bose-Einstein condensate at all subcritica...
متن کاملBright and gap solitons and vortex formation in a superfluid Bose-Fermi mixture
Starting from a Lagrangian density of a superfluid Bose-Fermi mixture we derive a coupled set of nonlinear Schrödinger equations for the system. In the absense of interspecies Bose-Fermi interaction the Bose component satisfies a standard Gross-Pitaevskii equation, whereas the Fermi component satisfies a Ginzburg-Landau-type equation suitable for the Fermi superfluid. To study dynamics we use t...
