    Graduate Can Two Photons Really Form Bound States?

    With great interest I read an article about a paper where scientists were able to create two photon bound states ("molecules of light"). http://physicsworld.com/cws/article/news/2013/sep/26/physicists-create-molecules-of-light I was quite astonished since light normally does not...

    Graduate QED perturbation series convergence versus exact solutions

    It is well known due to the famous argument by Dyson that the perturbation series for quantum electrodynamics has zero radius of convergence. Dysons argument essentially goes like that: If the power series in α had a finite (r>0) radius of convergence it also would converge for some small...

    Graduate Neutrino Antineutrino annihilation possible?

    As far as I know, the anihilation of an electron by a positron is an electromagnetic process described by QED. Neutrinos, however, do not participate in the elektromagnetic interaction. Does that mean a Antineutrino will not anihilate a Neutrino of the same kind? Is there an interaction between...
