When I took freshman physics in 1983, my professor made an off-handed comment that Louis de Broglie's PhD thesis on the matter wave was only 3 pages long, and that it was the shortest PhD thesis ever in physics.
For some time now I've been trying to find a PhD of the thesis, which I presume is in German. I can't find it.
I have found the proper reference to his doctoral thesis, though. It appears to be:
L. de Broglie, “Recherches sur la théorie des quanta”, Thèse de doctorat soutenue à Paris, le 25 novembre 1924, Annales de Physique (10e série) III (1925) 22. Reproduced in: L. de Broglie, Recherches sur la théorie des quanta (Fondation Louis de Broglie, Paris, 1992).
I've searched online for that document, and I can't find it. I can find another publication with the same title, but it appears to be a book based on the PhD thesis, and not the thesis itself.
So what is the shortest PhD thesis in physics, and if it is de Broglie's, where can I find it?
