Multipartite entangled state representation and its squeezing transformation

The multipartite entangled state |p,χ2,χ3,…,χn〉 for the total momentum and relative coordinates of n particles is constructed. The corresponding quantum-mechanical operator with respect to the classical transformation p→eλ1p, χi→eλiχi, i=2,…,n, in the state |p,χ2,χ3,…,χn〉 is investigated.
