Energetics of three interacting mass-imbalanced bodies in a three-dimensional spherical harmonic trap
A. D. Kerin, A. M. Martin
We consider a system of three particles, either three identical bosons or two identical fermions plus an impurity, within a three-dimensional isotropic trap interacting via a conta…
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…
Two-body quench dynamics of harmonically trapped interacting particles
A. D. Kerin, A. M. Martin
We consider the quantum evolution of a pair of interacting atoms in a three dimensional isotropic trap where the interaction strength is quenched from one value to another. Using e…
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…
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…
Analysis of two and three dipolar bosons in a spherical harmonic trap
C. J. Bradly, H. M. Quiney, A. M. Martin
As dipolar gases become more readily accessible in experiment there is a need to develop a comprehensive theoretical framework of the few-body physics of these systems. Here, we ex…
Negative Refraction of Excitations in the Bose-Hubbard Model
R. A. Henry, J. Q. Quach, C-H. Su +2
Ultracold atoms in optical lattices provide a unique opportunity to study Bose- Hubbard physics. In this work we show that by considering a spatially varying onsite interaction it…
Coupled pair approach for strongly-interacting trapped fermionic atoms
C. J. Bradly, B. C. Mulkerin, A. M. Martin +1
We present a coupled pair approach for studying few-body physics in harmonically trapped ultracold gases. The method is applied to a two-component Fermi system of particles. A…
Vibrations of a Columnar Vortex in a Trapped Bose-Einstein Condensate
Lyndon Koens, Tapio P. Simula, Andrew M. Martin
We derive a governing equation for a Kelvin wave supported on a vortex line in a Bose-Einstein condensate, in a rotating cylindrically symmetric parabolic trap. From this solution…
Universality and itinerant ferromagnetism in rotating strongly interacting Fermi gases
B. C. Mulkerin, C. J. Bradly, H. M. Quiney +1
We analytically determine the properties of three interacting fermions in a harmonic trap subject to an external rotation. Thermodynamic quantities such as the entropy and energy a…
Interferometry using Adiabatic Passage in Dilute Gas Bose-Einstein Condensates
M. Rab, A. L. C. Hayward, J. H. Cole +2
We theoretically examine three-well interferometry in Bose-Einstein condensates using adiabatic passage. Specifically, we demonstrate that a fractional coherent transport adiabatic…
Perturbative behaviour of a vortex in a trapped Bose-Einstein condensate
Lyndon Koens, Andrew M. Martin
We derive a set of equations that describe the shape and behaviour of a single perturbed vortex line in a Bose-Einstein condensate. Through the use of a matched asymptotic expansio…
Coherent tunneling via adiabatic passage in a three-well Bose-Hubbard system
C. J. Bradly, M. Rab, A. D. Greentree +1
We apply the Bose-Hubbard Hamiltonian to a three-well system and show analytically that coherent transport via adiabatic passage (CTAP) of non-interacting particles across the…
