Quantization of mesoscopic quartz piezoelectric crystal equivalent circuit

Hongqi Li, 菏泽学院物理系,菏泽274015

By using the idea of damped harmonic oscillator operation,a mesoscopic quartz piezoelectric crystal equivalent circuit is quantized. By this basic theory, we studied the quantum fluctuation of the voltage and current in each branch of the mesoscopic quartz piezoelectric crystal equivalent circuit under the squeezed vacuum state and the vacuum state.

QUANTIZATION OF MESOSCOPIC QUARTZ PIEZOELECTRIC CRYSTAL EQUIVALENT CIRCUIT

Zhan-Yuan Yan, Ma Jin-Ying, XIAO-HONG ZHANG

In the framework of an advanced quantum theory for mesoscopic electric circuits in accord with the discreteness of electric charges, a mesoscopic quartz piezoelectric crystal equivalent circuit is quantized. To resolve the finite difference Schrödinger equation, an improved parameter perturbative method is proposed when WKB and perturbative method are inapplicable. With this method, the energy spectrum and wavefunctions of the system are obtained and used to calculate current quantum fluctuation as an application. The new method would be helpful to the application of the mesoscopic circuits quantum theory. Besides, the detail characters of energy spectrum and wavefunctions in the system would be helpful to the design of integrate circuit.

Quantum Fluctuations of Mesoscopic Parallel Connection LC Circuit in Thermal Vacuum State

Hongqi Li

Starting from the classical equation of motion, the mesoscopic parallel LC circuit is quantized. On this basic theory, we have studied quantum fluctuations of the voltage and current of each branch in thermal vacuum state. The result shows that the quantum fluctuations of the voltage and current of each branch are related with parameter of the circuit element, and also related with temperature and decayed with time.

By making use of the quantum canonic ensemble theory,the quantum fluctuations of a mesoscopic RLC circuit in the mixed state have been studied.It is shown that the quantum fluctuations of the mesoscopic RLC circuit depend on not only the circuit component parameters,but also on the temperature.The higher temperature,the more quantum noise the mesoscopic RLC circuit exhibits.
