    "abstract": "The dynamics of a particle interacting with random classical field in a\ntwo-well potential is studied by the functional integration method. The\nprobability of particle localization in either of the wells is studied in\ndetail. Certain field-averaged correlation functions for quantum-mechanical\nprobabilities and the distribution function for the probabilities of final\nstates (which can be considered as random variables in the presence of a random\nfield) are calculated. The calculated correlators are used to discuss the\ndependence of the final state on the initial state. One of the main results of\nthis work is that, although the off-diagonal elements of density matrix\ndisappear with time, a particle in the system is localized incompletely\n(wave-packet reduction does not occur), and the distribution function for the\nprobability of finding particle in one of the wells is a constant at infinite\ntime.",
