On the Cover

The image (a) shows a 0.4-mm long atom laser beam, generated by extracting atoms from the Bose-Einstein condensate at the top. The atoms in the BEC and the beam are in m_F = 0 spin states, making this laser (unlike earlier ones) insensitive to stray magnetic fields. The graph (b) depicts the beam's transverse spread, expected to be limited only by the uncertainty principle.
