Emergence of giant vortices under nonlinear rotation with attractive interactions in a toroidal condensate
Rony Boral, Swarup K. Sarkar, Matthew Edmonds +2
We numerically investigate the effects of a density-dependent gauge potential which induces nonlinear rotation on a Bose-Einstein condensate confined in a toroidal trapping geometr…
Photoacoustic model for laser-induced acoustic desorption of nanoparticles
Matthew Edmonds, James Bateman
Laser-induced acoustic desorption (LIAD) enables loading nanoparticles into optical traps under vacuum for levitated optomechanics experiments. Current LIAD systems rely on empiric…
Dark quantum droplets and solitary waves in beyond-mean-field Bose-Einstein condensate mixtures
Matthew Edmonds
Quantum liquid-like states of matter have been realized in an ongoing series of experiments with ultracold Bose gases. Using a combination of analytical and numerical methods we id…
Quantum droplets of quasi-one-dimensional dipolar Bose-Einstein condensates
Matthew Edmonds, Thomas Bland, Nick G. Parker
Ultracold dipolar droplets have been realized in a series of ground-breaking experiments, where the stability of the droplet state is attributed to beyond-mean-field effects in the…
Quantum vacuum effects in non-relativistic quantum field theory
Matthew Edmonds, Antonino Flachi, Marco Pasini
Nonlinearities in the dispersion relations associated with different interactions designs, boundary conditions and the existence of a physical cut-off scale can alter the quantum v…
Few-to-many vortex states of density-angular-momentum coupled Bose-Einstein condensates
Matthew Edmonds
Motivated by recent experiments, we theoretically study a gas of atomic bosons confined in an elliptical harmonic trap; forming a quasi-two-dimensional atomic Bose-Einstein condens…
Quantum vacuum, rotation, and nonlinear fields
Antonino Flachi, Matthew Edmonds
In this paper, we extend previous results on the quantum vacuum or Casimir energy, for a noninteracting rotating system and for an interacting nonrotating system, to the case where…
Polar core vortex dynamics in disc-trapped homogeneous spin-1 Bose-Einstein condensates
Matthew Edmonds, Lewis A. Williamson, Matthew J. Davis
We study the dynamics of polar core vortices in the easy plane phase of an atomic spin-1 Bose-Einstein condensate confined in a two-dimensional disc potential. A single vortex move…
Vortex patterns of atomic Bose-Einstein condensates in a density-dependent gauge potential
Matthew Edmonds, Muneto Nitta
We theoretically examine the vortex states of a gas of trapped quasi-two-dimensional ultracold bosons subject to a density-dependent gauge potential, realizing an effective nonline…
Synthetic superfluid chemistry with vortex-trapped quantum impurities
Matthew Edmonds, Minoru Eto, Muneto Nitta
We explore the effect of using two-dimensional matter-wave vortices to confine an ensemble of bosonic quantum impurities. This is modelled theoretically using a mass-imbalanced hom…
Elementary excitations of chiral Bose-Einstein condensates
Matthew Edmonds, Manuel Valiente, Patrik Ãhberg
We study the collective modes of a Bose-Einstein condensate subject to an optically induced density-dependent gauge potential. The corresponding interacting gauge theory lacks Gali…
Quantum droplets in a beyond-mean-field density-dependent gauge theory
Matthew Edmonds, Patrik Ãhberg
The beyond-mean-field corrections appropriate to a bosonic many-body system experiencing a density-dependent gauge potential are derived, and from this the dimensional hierarchy of…
On the Josephson effect in a Bose-Einstein condensate subject to a density dependent gauge potential
Matthew Edmonds, Manuel Valiente, Patrik Ohberg
We investigate the coherent dynamics of a Bose-Einstein condensate in a double well, subject to a density dependent gauge potential. Further, we derive the nonlinear Josephson equa…
Excitation spectrum of vortex-lattice modes in a rotating condensate with a density-dependent gauge potential
Rony Boral, Swarup K. Sarkar, Matthew Edmonds +2
We investigate the collective excitation spectrum of a quasi-2D Bose-Einstein condensate trapped in a harmonic confinement with nonlinear rotation induced by a density-dependent ga…
Simulating an interacting gauge theory with ultracold Bose gases
Matthew Edmonds, Manuel Valiente, Gediminas Juzeliunas +2
We show how density dependent gauge potentials can be induced in dilute gases of ultracold atoms using light-matter interactions. We study the effect of the resulting interacting g…
