摘要: 应用Wigner函数边缘分布理论研究了有限温度下的介观LC电路.结果表明Wigner函数对电路中p^2/2L和q^2/2C的边缘分布统计平均恰是分别储存在电感和电容中与温度有关的能量.

Abstract: The marginal distribution of Winger function in mesoscopic LC circuit at a finite temperature is in- vestigated by means of the Wigner function. The results show that the marginal distributions statistical average for p^2/2L and q^2/2C of the Wigner function are exactly the energy stored in inductance and capacity of the mesoscopic LC circuit, respectively at finite temperature.

Key words: Wigner function, marginal distribution, application, mesoscopic LC circuit
