# Observation of Interference Between Two Bose Condensates

@article{Andrews1997ObservationOI, title={Observation of Interference Between Two Bose Condensates}, author={M. R. Andrews and Christopher Townsend and H. J. Miesner and Dallin Durfee and Dan M. Kurn and Wolfgang Ketterle}, journal={Science}, year={1997}, volume={275}, pages={637 - 641} }

Interference between two freely expanding Bose-Einstein condensates has been observed. Two condensates separated by ∼40 micrometers were created by evaporatively cooling sodium atoms in a double-well potential formed by magnetic and optical forces. High-contrast matter-wave interference fringes with a period of ∼15 micrometers were observed after switching off the potential and letting the condensates expand for 40 milliseconds and overlap. This demonstrates that Bose condensed atoms are “laser…
