Reply to "Comment on "On a new definition of quantum entropy""
Michele Campisi
TL;DR
This paper responds to a comment on a previous work about quantum entropy, clarifying that negative temperature scenarios do not invalidate the Second Law of Thermodynamics.
Contribution
It clarifies misconceptions about quantum entropy and negative temperatures, reaffirming the robustness of the Second Law in such contexts.
Findings
Negative temperature systems obey the Law of Entropy Decrease
Negative temperatures do not challenge the Second Law
Clarification of quantum entropy concepts
Abstract
The example provided in the comment [arXiv:0803.2241] concerns a situation where the system is initially at negative temperature. It is known that in such cases the Law of Entropy Decrease holds. Nevertheless, this does not challenge the validity of the Second Law of Thermodynamics.
