We report on measurements of splitting Bose-Einstein condensates (BEC) by using a time-dependent optical lattice potential. First, we demonstrate the division of a BEC into a set of equally populated components by means of time dependent control of Landau-Zener tunneling in a vertical lattice potential. Next, we apply time dependent optical Bragg mirrors to a BEC oscillating in a harmonic trap. We demonstrate high-order Bragg reflection of the condensate due to multi-photon Raman transitions…

Observation of Atom Number Fluctuations in a Bose-Einstein Condensate.

A telltale signature of atom number fluctuations in Bose-Einstein condensates is observed: the sudden increase in fluctuations of the condensate atom number close to the critical temperature.

Fast and selective interband transfer of ultracold atoms in bichromatic lattices permitting Dirac points

An experimental group in Beijing [Yueyang Zhai et al., Phys. Rev. A 87, 063638 (2013)] introduced the method of the standing-wave pulse sequence for efficiently preparing ultracold bosonic atoms into

Non-destructive Faraday imaging of dynamically controlled ultracold atoms.

An easily implementable method for non-destructive measurements of ultracold atomic clouds based on dark field imaging of spatially resolved Faraday rotation is described and, in the absence of experimental imperfections, the sensitivity limit is found to be identical to other conventional dispersive imaging techniques.

Noise cancellation system for shaking optical lattice by controlling optical path.

It is demonstrated that the servo changes the relative phase between beams and follows the intended shaking function with 99% accuracy.

Accelerated and Airy-Bloch oscillations

A quantum particle subjected to a constant force undergoes an accelerated motion following a parabolic path, which differs from the classical motion just because of wave packet spreading (quantum

Loading ultracold atoms onto nonlinear Bloch states and soliton states in bichromatic lattices

We simulate and analyze an experimental method of loading interacting ultracold atoms onto nontrivial quantum states such as nonlinear Bloch wave and soliton solutions in a 1-dimensional bichromatic
