Sagnac interferometry using bright matter-wave solitons.

Helm, J.L. and Cornish, S.L. and Gardiner, S.A. (2015) 'Sagnac interferometry using bright matter-wave solitons.', Physical review letters., 114 (13). p. 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 potentials. In particular, we present an analytical and numerical analysis of the phase evolution of the solitons and delimit a velocity regime in which soliton Sagnac interferometry is possible, taking account of the effect of quantum uncertainty.
