Ergodic theorem in quantum mechanics. Evaluation of the probability of an exceptional initial condition

  • Published:
Il Nuovo Cimento (1955-1965)

Summary

In this paper an evaluation is made of the probability of finding an exceptional initial condition in the sense of the Bocchieri-Loinger formulation of the quantum ergodic theorem. The result is compared with that obtained byPauli andFierz who made a corresponding evaluation of the probability of finding a non-thermodynamical macro-observer in the original von Neumann formulation.

Riassunto

In questo lavoro si dà una valutazione della probabilità di trovare una condizione iniziale eccezionale, nel senso della formulazione di Bocchieri e Loinger del teorema ergodico quantistico. Si confrontano i risultati con quelli ottenuti daPauli eFierz che hanno dato una valutazione della probabilità di trovare un macro-osservatore non termodinamico nella formulazione originale divon Neumann.
