用广义Hellmann-Feynman定理导出量子化RLC电路中熵随电阻的变化

Entropy-variation with respect to the resistance in quantized RLC circuit derived by generalized Hellmann-Feynman theorem

Hong-yi Fan, Xue-xiang Xu, Li-yun Hu

摘要:

利用推广的Hellmann-Feynman系综平均定理,得到了量子化RLC电路中电阻R的内能和平均能量。我们还计算了相对于R的熵变差。并导出了熵与R的关系。通过描绘图形,我们确实看到熵随R的增加而增加。

英文摘要:

By virtue of the generalized Hellmann-Feynman theorem for ensemble average, we obtain internal energy and average energy consumed by the resistance R in a quantized RLC electric circuit. We also calculate entropy-variation with respect to R. The relation between entropy and R is also derived. By depicting figures we indeed see that the entropy increases with the increment of R.
