Emergence of classical trajectories in quantum systems: the cloud chamber problem in the analysis of Mott (1929)    [PDF]

Rodolfo Figari, Alessandro Teta
We analyze the paper "The wave mechanics of $\alpha$-ray tracks" (Mott, 1929), published in 1929 by N.F. Mott. In particular, we discuss the theoretical context in which the paper appeared and give a detailed account of the approach used by the author and the main result attained. Moreover, we comment on the relevance of the work not only as far as foundations of Quantum Mechanics are concerned but also as the earliest pioneering contribution in decoherence theory.
