Abstract

It has been claimed that measurements of trapped magnetic flux in hydrides under pressure provide evidence for superconductivity in these materials (Minkov et al., 2022; Minkov et al., 2023). In recent work we have questioned that claim (Hirsch and Marsiglio, 2022). Here we point out that recent experiments (Bud’ko et al., 2023) provide further evidence supporting our questioning of that claim. We also present calculations for a thin disk and compare these with those previously calculated for a long cylinder. The results are qualitatively similar, and therefore reinforce our previous conclusions. We also address recent criticism of our paper Ref. (Hirsch and Marsiglio, 2022) by Bud’ko (2024) and by Talantsev et al. (2023).

高压下氢化物通量捕获实验的进一步分析

有人声称，对氢化物在压力下的捕获磁通量的测量为这些材料的超导性提供了证据（Minkov 等人，2022 年；Minkov 等人，2023 年）。在最近的研究中，我们对这一说法提出了质疑（Hirsch 和 Marsiglio，2022 年）。我们在此指出，最近的实验（Bud'ko 等人，2023 年）提供了进一步的证据，支持我们对这一说法的质疑。我们还提出了对薄圆盘的计算结果，并与之前对长圆柱体的计算结果进行了比较。结果在质量上是相似的，因此加强了我们之前的结论。我们还回应了最近Bud'ko（2024）和Talantsev等人（2023）对我们论文Ref.（Hirsch and Marsiglio, 2022）的批评。

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.
