Squeezing effects of the mesoscopic LC circuit

According to the fact that a mesoscopic capacitor can be regarded as a mesoscopic junction, we restudied the quantum effects of the mesoscopic LC circuit. The study shows: considering the coupling effects of the mesoscopic capacitor, the mesoscopic LC circuit will evolve from the vacuum state to a squeezing vacuum state. We also research the quantum fluctations of the squeezing vacuum state.
