[Cnqo] Optics division seminar next week:

[Paul Griffin]

Evening all,

Next week Simon Gardiner, from Durham University, will be giving the Optics Division seminar. Simon will be in the department from Wednesday afternoon and will be available for discussion - please let me know if you would like to schedule some time

Speaker: Simon Gardiner, Durham
Date: Wednesday, 4th November
Time: 3pm
Location: JA8.13 - SUPA Room
Title: Bright Matter-Wave Solitons, Interferometry, and Rotational Sensing
Abstract:
An ultracold ensemble of bosonic atoms can condense into a Bose-Einstein condensate, where it is frequently legitimate to use a classical field description, encapsulated in the Gross-Pitaevskii equation. In certain limiting geometries this tends to the one-dimensional nonlinear Schrodinger equation, which in the case of attractive atom-atom interactions, supports bright soliton solutions.  These attractively particle-like wave-forms have a number of advantages when considering the possibility of matter-wave interferometry --- using atoms or molecules rather than light to make interference measurements.  I will talk about some of the issues surrounding such interferometric protocols, discussing Sagnac interferometry (for rotational sensing) as a particular example.

regards,
Griff
