Towards an improved test of Bose-Einstein statistics for photons

In this contribution we describe our current efforts at Berkeley to improve upon a limit on Bose-Einstein statistics violation for photons obtained earlier (D. P. DeMille, D. Budker, N. Derr, and E. Deveney, Phys. Rev. Lett. 83(20), 1378 (1999)). The principle differences between the new and the previous experiments are the use of a narrow-band cw laser, an atomic beam, a different transition in atomic Ba, and possibly a different detection technique. We also discuss the ultimate limits that one can hope to obtain with this degenerate two-photon transition technique. Some potential conceptual difficulties with the interpretation of this experiment and the ways to avoid them are discussed as well.
