摘要

在《熵》24,83 (2022)（Nikulov 2022）中，题为“熵增加定律和迈斯纳效应”的作者Alexey Nikulov认为，I型超导体表现出的迈斯纳效应违反了热力学第二定律。与这种说法相反，我证明迈斯纳效应与热力学第二定律是一致的，前提是存在一种机制，使超电流在不产生焦耳热的情况下启动和停止。空穴超导理论提供了这样一种机制，而传统的超导理论没有。它要求在系统的正常状态下存在空穴载流子。

Does the Meissner effect violate the second law of thermodynamics?

In Entropy 24, 83 (2022) (Nikulov 2022), titled “The Law of Entropy Increase and the Meissner Effect”, its author Alexey Nikulov argues that the Meissner effect exhibited by type I superconductors violates the second law of thermodynamics. Contrary to this claim, I show that the Meissner effect is consistent with the second law of thermodynamics provided that a mechanism exists for the supercurrent to start and stop without generation of Joule heat. The theory of hole superconductivity provides such a mechanism, the conventional theory of superconductivity does not. It requires the existence of hole carriers in the normal state of the system.

期刊介绍： Physica C (Superconductivity and its Applications) publishes peer-reviewed papers on novel developments in the field of superconductivity. Topics include discovery of new superconducting materials and elucidation of their mechanisms, physics of vortex matter, enhancement of critical properties of superconductors, identification of novel properties and processing methods that improve their performance and promote new routes to applications of superconductivity. The main goal of the journal is to publish: 1. Papers that substantially increase the understanding of the fundamental aspects and mechanisms of superconductivity and vortex matter through theoretical and experimental methods. 2. Papers that report on novel physical properties and processing of materials that substantially enhance their critical performance. 3. Papers that promote new or improved routes to applications of superconductivity and/or superconducting materials, and proof-of-concept novel proto-type superconducting devices. The editors of the journal will select papers that are well written and based on thorough research that provide truly novel insights.
