Author Response
We appreciate the comments of the reviewer to our manuscript. There are two issues pointed out in his report and our answer follows:
- We agree that the reference to the fluctuation-dissipation theorem may be obviated, and can be misleading. We deleted that sentence.
- We have corrected the word ¨conduces´ indicated by the reviewer.
Also, we attached a corrected version with the changes highlighted in red.
Reviewer 2 Report
This paper continues the study of Casimir interaction ofhigh-temperature YBCO superconductors initiated in Ref.[31].
Here, the potential influence of varying damping parameters is
investigated. I find the results interesting. However, a couple of
points have to be clarified, see below. One point refers to the use of term "Drude-plasma controversy" all
over the text. Of course, the use of Drude vs plasma model is a
controversial issue in the Casimir physics in general, with regard
to both the zero-temperature limit and the comparison with
experimental data. This controversy has to be mentioned somewhere,
but repeating these words too frequently will make the reader confused.
There is nothing controversial in the present context. It is interesting to see considerable variation of the Casimir force
at large separations with the change of $\gamma_p$. Could the authors
comment on how well the value of this parameter is known?
Author Response
We appreciate the carful reading of the manuscript and have made the changes suggested bu the reviewer. There were two issues pointed out by the reviewer and
- The term plasma-Drude controversy can be misleading, as mentioned by the reviewer. In a way, if there is experimental evidence favoring the plasma description then, there is no controversy in the context of the paper. So we avoided the term controversy and emphasize that the main purpose of the manuscript is to further understand the role of the electronic relaxation in the Casimir force calculations. The changes are indicated in red.
- About the values of $\gamma_p$ (see lines 113-115) we indicate in the manuscript that the values we use correspond to polycrystalline YBCO, but the variations of $\gamma_p$ as reported in Ref.[41]. Indeed, the value ranges from 0.03 eV to 0.035 eV and are obtained from the best fit to experimental data.
