标题： Physical interpretation of large Lorentz violation via Weyl semimetals

摘要： 基本相互作用的有效场论中包含大洛伦兹破缺的物理解释是一个长期存在的挑战，称为协调问题。 在凝聚态物理中，某些具有涌现洛伦兹不变性的外尔半金属表现出大的洛伦兹破缺，从而为探索这一问题提供了有前景的实验室类比。 我们利用基本物理和凝聚态物理中大洛伦兹破缺描述之间的数学等价性，来研究当洛伦兹破缺系数较大或观察者参考系高度增强时出现的协调问题的主要方面。 通过热力学论证，我们提出了一个解决协调问题的物理方案并探讨了一些含义。 显示英文摘要

摘要： The physical intepretation of effective field theories of fundamental interactions incorporating large Lorentz violation is a long-standing challenge, known as the concordance problem. In condensed-matter physics, certain Weyl semimetals with emergent Lorentz invariance exhibit large Lorentz violation, thereby offering prospective laboratory analogues for exploration of this issue. We take advantage of the mathematical equivalence between the descriptions of large Lorentz violation in fundamental and condensed-matter physics to investigate the primary aspects of the concordance problem, which arise when the coefficients for Lorentz violation are large or the observer frame is highly boosted. Using thermodynamic arguments, we present a physical solution to the concordance problem and explore some implications.
