WEYL CORRESPONDENCE AND PATH-INTEGRAL FOR 2-MODE CORRELATED SYSTEM

The Weyl correspondence and Wigner operator theory for two-mode correl ated system is developed on the common eigenstate basis [eta\ of two p articles' total momentum and relative position. The development brings much convenience for calculating the Wigner functions of some two-mod e correlated states and makes some Weyl correspondence derivation poss ible. Correspondingly, the path integral with midpoint prescription in [eta\ representation is also formulated.
