Coherent Control of Domain-Wall Transport in an Ultracold Bose Gas
O. Farion, M. Pourzand, J. M. McGuirk
Domain walls are carriers of spin transport whose controlled manipulation underlies a wide range of spintronic and information-processing technologies. Here we demonstrate tunable…
Stable spin domains in a non-degenerate ultra-cold gas
S. D. Graham, D. Niroomand, R. J. Ragan +1
We study the stability of two-domain spin structures in an ultra-cold gas of magnetically trapped Rb atoms above quantum degeneracy. Adding a small effective magnetic field…
Retardation effects in induced atomic dipole-dipole interactions
S. D. Graham, J. M. McGuirk
We present mean-field calculations of azimuthally averaged retarded dipole-dipole interactions in a Bose-Einstein condensate induced by a laser, at both long and short wavelengths.…
Longitudinal spin diffusion in a nondegenerate trapped Rb gas
D. Niroomand, S. D. Graham, J. M. McGuirk
Longitudinal spin diffusion of two pseudo-spin domains is studied in a trapped Rb sample above quantum degeneracy, and the effect of coherence in the domain wall on the dyna…
Localized collapse and revival of coherence in an ultracold Bose gas
J. M. McGuirk, L. F. Zajiczek
We study the collapse and revival of coherence induced by dipolar spin waves in a trapped gas of Rb-87 atoms. In particular we observe spatially localized collapse and revival of R…
Optical excitation of nonlinear spin waves
J. M. McGuirk, L. F. Zajiczek
We demonstrate a technique for exciting spin waves in an ultracold gas of Rb-87 atoms based on tunable AC Stark potentials. This technique allows us to excite normal modes of spin…
