The basic invariants and stable squeezed states
Abstract
A new concept of the basic invariants is introduced. With the help of the basic invariants, we construct the stable squeezed state for a system with time-dependent Hamiltonian. This state is the eigenstate of a basic invariant. Then the basic invariants are used to obtain a general form of invariants which in turn can be applied to discuss the high- n squeezed state.
