Abstract

We provide a pedagogical review article on fundamentals and applications of the quantum dynamics in strong electromagnetic fields in QED and QCD. The fundamentals include the basic picture of the Landau quantization and the resummation techniques applied to the class of higher-order diagrams that are enhanced by large magnitudes of the external fields. We then discuss observable effects of the vacuum fluctuations in the presence of the strong fields, which consist of the interdisciplinary research field of nonlinear QED. We also discuss extensions of the Heisenberg–Euler effective theory to finite temperature/density and to non-Abelian theories with some applications. Next, we proceed to the paradigm of the dimensional reduction emerging in the low-energy dynamics in the strong magnetic fields. The mechanisms of superconductivity, the magnetic catalysis of the chiral symmetry breaking, and the Kondo effect are addressed from a unified point of view in terms of the renormalization-group method. We provide an up-to-date summary of the lattice QCD simulations in magnetic fields for the chiral symmetry breaking and the related topics as of the end of 2022. Finally, we discuss novel transport phenomena induced by chiral anomaly and the axial-charge dynamics. Those discussions are supported by a number of appendices.

QED和QCD中的强场物理:从基础到应用

本文就强电磁场中量子动力学的基本原理及其在QED和QCD中的应用进行了教学综述。基础包括朗道量化的基本图像和应用于高阶图类的恢复技术，这些高阶图被大幅度的外场增强。然后讨论了强场存在下真空涨落的可观测效应，这是非线性QED的跨学科研究领域。我们还讨论了海森堡-欧拉有效理论在有限温度/密度和非阿贝尔理论中的推广及其一些应用。接下来，我们继续讨论在强磁场中低能动力学中出现的降维范式。用重整化基团的方法从统一的角度讨论了超导机制、手性对称性破缺的磁催化和近藤效应。我们提供了截至2022年底的手性对称性破缺的磁场晶格QCD模拟和相关主题的最新总结。最后讨论了由手性异常和轴电荷动力学引起的新型输运现象。这些讨论得到了一些附录的支持。

期刊介绍： Taking the format of four issues per year, the journal Progress in Particle and Nuclear Physics aims to discuss new developments in the field at a level suitable for the general nuclear and particle physicist and, in greater technical depth, to explore the most important advances in these areas. Most of the articles will be in one of the fields of nuclear physics, hadron physics, heavy ion physics, particle physics, as well as astrophysics and cosmology. A particular effort is made to treat topics of an interface type for which both particle and nuclear physics are important. Related topics such as detector physics, accelerator physics or the application of nuclear physics in the medical and archaeological fields will also be treated from time to time.
