Quantum fluctuations of general quantized mesoscopic RLC parallel circuit in thermal vaccum state

Abstract

Abstract:

The quantum effects of the general quantized mesoscopic RLC parallel circuit were studied base on the thermal field dynamics theory. The quantum fluctuations of the voltage and the current in each branch which depended on the factors such as the elements of the circuit, the thermal vaccum state and the time were analyzed. The results show that the quantum fluctuations in each brand are affected by all the three factors with follow regularity when the quantized mesoscopic circuit in the thermal vaccum state. The fluctuations decay with time exponentially, but the decay rate have relation to the elements of the circuit only. The amplitude of the fluctuations at the initial moment are depend on the elements of the circuit and the temperature of the thermal vaccum state.

Key words: quantum optics, quantum fluctuation, mesoscopic RLC parallel circuit, thermal vacuum state, dissipative resistance
