Optical detection of fractional particle number in an atomic Fermi-Dirac gas
Juha Javanainen, Janne Ruostekoski
We study theoretically a Fermi-Dirac atomic gas in a one-dimensional optical lattice coupled to a coherent electromagnetic field with a topologically nontrivial soliton phase profi…
Dirac monopoles and dipoles in ferromagnetic spinor Bose-Einstein condensates
C. M. Savage, J. Ruostekoski
We investigate a radial spin hedgehog, analogous to the Dirac monopole, in an optically trapped atomic spin-1 Bose-Einstein condensate. By joining together a monopole-antimonopole…
Monopole core instability and Alice rings in spinor Bose-Einstein condensates
J. Ruostekoski, J. R. Anglin
We show how the length scale hierarchy, resulting from different interaction strengths in an optically-trapped spin-1 sodium-23 Bose-Einstein condensate, can lead to intriguing cor…
Pulsed Raman output coupler for an atom laser
J. Ruostekoski, T. Gasenzer, D. A. W. Hutchinson
We theoretically study a pulsed stimulated two-photon Raman outcoupler for an atom laser using a full three-dimensional description. A finite-temperature trapped Bose-condensed ato…
Energetically stable particle-like Skyrmions in a trapped Bose-Einstein condensate
C. M. Savage, J. Ruostekoski
We numerically show that a topologically nontrivial 3D Skyrmion can be energetically stable in a trapped two-component atomic Bose-Einstein condensate, for the parameters of Rb-87…
