Bose Einstein Condensation at Georgia Institute of Technology

Images supplied by Chapman Research Labs, Prof. Michael Chapman's research group at the School of Physics, Georgia Institute of Technology (Georgia Tech) in Atlanta, Georgia.

Prof Chapman's research is focused on investigating the quantum behavior of atoms and photons, often at the single particle level. Lasers are employed to confine and cool atoms to nano-Kelvin temperatures, which are used for studies including fundamental atom-photon interactions, atom optics and interferometry, and quantum computing and communication.

A Bose-Einstein condensate of 17,000 rubidium-87 atoms is created directly in a 1-D optical lattice formed by two counter-propagating CO2 laser beams. The absorption image shown here here is taken 10 ms after the condensate is released from the optical trap.

Low-light fluorescence image of one million trapped rubidium atoms
Low-light fluorescence image of one million trapped rubidium atoms cooled to micro Kelvin temperatures. The gaseous atoms are confined at the intersection of three focused, off-resonant laser beams, and the image was taken by briefly illuminating the atoms with resonant laser light.
