Cooperative ordering in lattices of interacting two-level dipoles (2015)
Journal Article
Bettles, R., Gardiner, S., & Adams, C. (2015). Cooperative ordering in lattices of interacting two-level dipoles. Physical Review A, 92(6), Article 063822. https://doi.org/10.1103/physreva.92.063822

We investigate the cooperative behavior of regular monolayers of driven two-level dipoles, using classical electrodynamics simulations. The dipolar response results from the interference of many cooperative eigenmodes, each frequency-shifted from the...

From short-time diffusive to long-time ballistic dynamics: The unusual center-of-mass motion of quantum bright solitons (2015)
Journal Article
Weiss, C., Gardiner, S., & Breuer, H. (2015). From short-time diffusive to long-time ballistic dynamics: The unusual center-of-mass motion of quantum bright solitons. Physical Review A, 91(6), Article 063616. https://doi.org/10.1103/physreva.91.063616

Brownian motion is ballistic on short time scales and diffusive on long time scales. Our theoretical investigations indicate that one can observe the exact opposite—an “anomalous diffusion process” where initially diffusive motion becomes ballistic o...

Analysis beyond the Thomas-Fermi approximation of the density profiles of a miscible two-component Bose-Einstein condensate (2015)
Journal Article
Polo, J., Ahufinger, V., Mason, P., Sridhar, S., Billam, T., & Gardiner, S. (2015). Analysis beyond the Thomas-Fermi approximation of the density profiles of a miscible two-component Bose-Einstein condensate. Physical Review A, 91(5), Article 053626. https://doi.org/10.1103/physreva.91.053626

We investigate a harmonically trapped two-component Bose-Einstein condensate within the miscible regime, close to its boundaries, for different ratios of effective intra- and interspecies interactions. We derive analytically a universal equation for... Read More about Analysis beyond the Thomas-Fermi approximation of the density profiles of a miscible two-component Bose-Einstein condensate.

Sagnac interferometry using bright matter-wave solitons (2015)
Journal Article
Helm, J., Cornish, S., & Gardiner, S. (2015). Sagnac interferometry using bright matter-wave solitons. Physical Review Letters, 114(13), Article 134101. https://doi.org/10.1103/physrevlett.114.134101

We use an effective one-dimensional Gross-Pitaevskii equation to study bright matter-wave solitons held in a tightly confining toroidal trapping potential, in a rotating frame of reference, as they are split and recombined on narrow barrier potential...
