关于"金属能斯特热定理的分析和数值验证“的评论
Comment on ``Analytical and numerical verification of the Nernst heat theorem for metals''
摘要:
最近,Høye、Brevik、Ellingsen和Aarseth(quant-ph/0703174)声称,根据能斯特定理,使用Drude介电函数会导致零温度下的Casimir熵为零。我们证明,他们的证明是不适用于金属与完美的晶格没有杂质。因此,没有任何矛盾与以前的结果在文献中证明,德鲁德介电函数违反能斯特定理的Casimir熵的情况下,完美的晶格。我们还指出了错误的金属杂质的渐近表达式的系数。
英文摘要:
Recently, Høye, Brevik, Ellingsen and Aarseth (quant-ph/0703174) claimed that the use of the Drude dielectric function leads to zero Casimir entropy at zero temperature in accordance with Nernst's theorem. We demonstrate that their proof is not applicable to metals with perfect crystal lattices having no impurities. Thus there is no any contradiction with previous results in the literature proving that the Drude dielectric function violates the Nernst theorem for the Casimir entropy in the case of perfect crystal lattices. We also indicate mistakes in the coefficients of their asymptotic expressions for metals with impurities.
