تماشای ویدئو Bose Einstein Condensate Coldest Place in the Universe از آی-ویدئو

A short video explaining how a Bose-Einstein Condensate of sodium atoms is created in lab at MIT by Martin Zwierlein. Using highly focused, single frequency lasers it is possible to cool the single sodium atoms, negating their thermal vibrations by inducing electronic transitions which effectively "pushes" them into place. This brings the atoms down to millikelivn temperatures. However to achieve nanokelvin temperatures, magnetic fields are used to trap the atoms in a well or cup so that the a
