Abstract

We develop a method which allows us to deal with a constrained manyparticle system We use the projector technique together with the path integral formulation to obtain the quantum dynamics of holonomic and nonholonomic systems In the nonholonomic case Feynmans integrals are defined only locally and the wave function acquires a pathdependent phase factorМы развиваем метод который позволяет нам рассмотреть ограниченную многочастичную систему Мы используем технику проектора вместе с формализмом интегрирования по траекториям для получения квантовой динамики голономых и неголономных систем В неголономном случае интегралы Фейнмана определяются только локально а волновая функция имеет фазовый множитель зависящий от траекторииSi sviluppa un metodo che permette di trattare con un sistema a molte particelle vincolato Si usa la tecnica del proiettore insieme alla formulazione dellintegrale di percorso per ottenere la dinamica quantistica di sistemi olonomi e non olonomi Nel caso non olonomo gli integrali di Feynman sono definiti solo localmente e la funzione donda acquisisce un fattore di fase dipendente dal percorso
