Axially confined binary quantum droplets: ground states and central vortices
Srivatsa B. Prasad, Thomas P. Billam, Nick G. Parker
Ultracold miscible mixtures of bosonic gases have been observed to form quantum droplet states stabilized by beyond-mean-field quantum fluctuations. Here we study the properties of…
Crow instability of vortex lines in dipolar superfluids
Srivatsa B. Prasad, Nick G. Parker, Andrew W. Baggaley
In classical inviscid fluids, antiparallel vortices perturbed by Kelvin waves exhibit the Crow instability, where the mutual interaction of the Kelvin modes renders them dynamicall…
Vortex pair dynamics in three-dimensional homogeneous dipolar superfluids
Srivatsa B. Prasad, Nick G. Parker, Andrew W. Baggaley
The static and dynamic properties of vortices in dipolar Bose-Einstein condensates (dBECs) can be considerably modified relative to their nondipolar counterparts by the anisotropic…
Vortex depinning in a two-dimensional superfluid
I-Kang Liu, Srivatsa B. Prasad, Andrew W. Baggaley +2
We employ the Gross--Pitaevskii theory to model a quantized vortex depinning from a small obstacle in a two-dimensional superfluid due to an imposed background superfluid flow. We…
Arbitrary-angle rotation of the polarization of a dipolar Bose-Einstein condensate
S. B. Prasad, B. C. Mulkerin, A. M. Martin
We have employed the theory of harmonically trapped dipolar Bose-Einstein condensates to examine the influence of a uniform magnetic field that rotates at an arbitrary angle to its…
Stationary states, dynamical stability, and vorticity of Bose-Einstein condensates in tilted rotating harmonic traps
Srivatsa B. Prasad, Brendan C. Mulkerin, Andrew M. Martin
We theoretically investigate a Bose-Einstein condensate confined by a rotating harmonic trap whose rotation axis is not aligned with any of its principal axes. The principal axes o…
Vortex Lattice Formation in Dipolar Bose-Einstein Condensates via Rotation of the Polarization
Srivatsa B. Prasad, Thomas Bland, Brendan C. Mulkerin +2
The behaviour of a harmonically trapped dipolar Bose-Einstein condensate with its dipole moments rotating at angular frequencies lower than the transverse harmonic trapping frequen…
Instability of Rotationally Tuned Dipolar Bose-Einstein Condensates
S. B. Prasad, T. Bland, B. C. Mulkerin +2
The possibility of effectively inverting the sign of the dipole-dipole interaction, by fast rotation of the dipole polarization, is examined within a harmonically trapped dipolar B…
Effective Three-Body Interactions in Jaynes-Cummings-Hubbard Systems
Srivatsa B. Prasad, Andrew M. Martin
A generalisation of the Jaynes-Cummings-Hubbard model for coupled-cavity arrays is introduced, where the embedded two-level system in each cavity is replaced by a -type three-le…
