Bose-Einstein Condensation of Molecules

Science, 2003
We report on the Bose-Einstein condensation of more than 10 5 Li 2 molecules in an optical trap starting from a spin mixture of fermionic lithium atoms. During forced evaporative cooling, the molecules are formed by three-body recombination near a Feshbach resonance and finally condense in a ...

Bose–Einstein condensation

Bose–Einstein condensation embodies some of the most fascinating aspects of quantum mechanics. Predicted 100 years ago, its experimental realization in 1995 opened up unexpected directions in both fundamental and applied quantum physics. This chapter describes the main features of Bose–Einstein condensation, focusing on its experimental realization in ...

Visualizing Bose-Einstein condensates

Computing in Science & Engineering, 2003
We present a method for visualizing numerical simulations of Bose-Einstein condensates, discuss the visualization process, which includes selecting a color scheme and the application of a volume rendering model, and describe our visualization's impact on associated scientific research.

Bose-Einstein Condensation in Microgravity

Science, 2010
Going Down the Tube Two pillars of modern physics are quantum mechanics and general relativity. So far, both have remained apart with no quantum mechanical description of gravity available. Van Zoest et al. (p. 1540 ; see the Perspective by

Interference of Bose−Einstein Condensates

The Journal of Physical Chemistry B, 2008
A formalism for describing the coherence and interference properties of two atomic clouds of Bose-Einstein condensates (BEC) is presented, which is applicable even in the opposite limits when the BEC clouds are initially coherent and when they are initially independent. First, we develop a mean-field theory wherein one mean-field mode is used, and then,

Bose-Einstein Condensation of Cesium

Science, 2003
Bose-Einstein condensation of cesium atoms is achieved by evaporative cooling using optical trapping techniques. The ability to tune the interactions between the ultracold atoms by an external magnetic field is crucial to obtain the condensate and offers intriguing features for potential applications.

Properties of a Bose–Einstein Condensate

2000
By cooling down a collection of integer spin atoms to a temperature of less than one micro-Kelvin, one can observe the phenomenon of Bose—Einstein condensation. This results in a situation where a large fraction of the atoms are in the same quantum state. Consequently, the system possesses remarkable coherence properties. We study here the ground state
