  1. Photons in a permutation anti-symmetric state?and What would a quantum-statistic violation mean? Inauguration Meeting Iceland, July 2007 Dmitry Budker http://socrates.berkeley.edu/~budker Support: N$F

  2. Identical particles: the ultimate equality • Individualism: the ultimate diversity • Permutation symmetry postulate • Spin-Statistics Theorem (SST)

  3. Prof. Richard P. Feynman(1918-1988) Feynman’s Lectures on Physics, V. 3:

  4. Okun’ on Pauli

  5. Doesn’t go because no symmetric statefor two photons with J=1 Landau, L. D., Dokl. Akad. Nauk., USSR 60, 207-209 (1948) How? Landau-Yang Theorem!

  6. S. N. Bose Landau-Yang theorem and the degenerate two-photon transition selection rule • L-Y: V(J=1)  • Inverse L-Y: Nothing(J=0) +  V(J=1) • Destructive interference of two quantum paths

  7. 1999 DeMille 1

  8. Interaction region

  9. Lasers

  10. Results

  11. Results

  12. Numbers

  13. Damon English

  14. Disturbing Questions • No consistent relativistic theory accommodating a statistics violation • How to compare with other experiments? (Z→γγ, …) • Constrains from lasers, BBR, static limit ? •  Need a generalized E&M theory
