Bloch oscillations of Bose-Einstein condensates: breakdown and revival.
نویسندگان
چکیده
We investigate the dynamics of Bose-Einstein condensates in a tilted one-dimensional periodic lattice within the mean-field (Gross-Pitaevskii) description. Unlike in the linear case the Bloch oscillations decay because of nonlinear dephasing. Pronounced revival phenomena are observed. These are analyzed in detail in terms of a simple integrable model constructed by an expansion in Wannier-Stark resonance states. We also briefly discuss the pulsed output of such systems for stronger static fields.

Bloch Waves and Bloch Bands of Bose-Einstein Condensates in Optical Lattices
Bose-Einstein condensates (BECs) in optical lattices have been attracting increasing attention from both theorists [1, 2, 3, 4, 5, 6, 7] and experimentalists [8, 9]. People are interested in how the interaction and coherence of this system affect the interesting phenomena observed with dilute cold atoms in optical lattices [10], such as LandauZener tunneling and Bloch oscillations. Recent studi...
متن کاملBeyond mean field physics with Bose-Einstein condensates in optical lattices
By loading Bose-Einstein condensates into a three dimensional optical lattice potential we are able to demonstrate several new intriguing regimes in the physics of ultracold atoms. For example by changing the lattice potential depth we have been able to induce a quantum phase transition from a superfluid to a Mott insulating ground state of the system. Furthermore, by rapidly isolating the diff...
متن کاملSelf-trapping of Bose-Einstein condensates expanding into shallow optical lattices
We observe a sudden breakdown of the transport of a strongly repulsive Bose-Einstein condensate through a shallow optical lattice of finite width. We are able to attribute this behavior to the development of a self-trapped state by using accurate numerical methods and an analytical description in terms of nonlinear Bloch waves. The dependence of the breakdown on the lattice depth and the intera...
متن کاملCoherence Times of Bose-Einstein Condensates beyond the Shot-Noise Limit via Superfluid Shielding.
We demonstrate a new way to extend the coherence time of separated Bose-Einstein condensates that involves immersion into a superfluid bath. When both the system and the bath have similar scattering lengths, immersion in a superfluid bath cancels out inhomogeneous potentials either imposed by external fields or inherent in density fluctuations due to atomic shot noise. This effect, which we cal...
متن کاملDiscrete solitons and breathers with dilute Bose-Einstein condensates.
We study the dynamical phase diagram of a dilute Bose-Einstein condensate (BEC) trapped in a periodic potential. The dynamics is governed by a discrete nonlinear Schrödinger equation: intrinsically localized excitations, including discrete solitons and breathers, can be created even if the BEC's interatomic potential is repulsive. Furthermore, we analyze the Anderson-Kasevich experiment [Scienc...
