Ⅰ. Characteristic function and squeezing
The concept of squeezing has been generatized to any quantum states of the rediation field using wigner characteristic function method. As and example, we have discussed the squeezing of the light field in a new quantum state, squeezed chaotio state. Physically the squeezing can be explained to be created by proton-mixing between the light and its phase conjugate field.
