Increasing the coherence time of Bose-Einstein-condensate interferometers with optical control of dynamics
TLDR
In this paper, the authors present a theoretical model that offers a physically simple explanation for the loss of contrast and propose the method for increasing the fringe contrast by recombining the atoms at a different time.Abstract:
Atom interferometers using Bose-Einstein condensate that is confined in a waveguide and manipulated by optical pulses have been limited by their short coherence times. We present a theoretical model that offers a physically simple explanation for the loss of contrast and propose the method for increasing the fringe contrast by recombining the atoms at a different time. A simple, quantitatively accurate, analytical expression for the optimized recombination time is presented and used to place limits on the physical parameters for which the contrast may be recovered.read more

Confinement effects in a guided-wave atom interferometer with millimeter-scale arm separation
TL;DR: In this paper, the authors investigate the effect of residual confinement along the nominally free axis of the atoms and show that it can be alleviated by having the atoms undergo a more symmetric motion in the guide, which is achieved by either using additional laser pulses or by allowing the atoms to freely oscillate in the potential.
