    "abstract": "In the optical Stern-Gerlach effect the two branches in which the incoming\natomic packet splits up can display interference pattern outside the cavity\nwhen a field measurement is made which erases the which-way information on the\nquantum paths the system can follow. On the contrary, the mere possibility to\nacquire this information causes a decoherence effect which cancels out the\ninterference pattern. A phase space analysis is also carried out to investigate\non the negativity of the Wigner function and on the connection between its\ncovariance matrix and the distinguishability of the quantum paths.",
