L. Accardi et Yg. Lu, THE FERMION NUMBER PROCESSES AS A FUNCTIONAL CENTRAL LIMIT OF QUANTUMHAMILTONIAN MODELS, Annales de l'I.H.P. Physique theorique, 58(2), 1993, pp. 127-153
In the present paper, we investigate, in the Fermion case, how the num
ber processes arise from a limit of a quantum Hamiltonian model. Our c
onclusion is that the time evolution of a certain quantum Hamiltonian
model tends to the solution of a quantum stochastic differential equat
ion driven by the Fermion number processes.
