相对论量子动力学:空间、时间、粒子、场和超距作用的非传统观点

Relativistic Quantum Dynamics: A non-traditional perspective on space, time, particles, fields, and action-at-a-distance

Eugene V. Stefanovich

摘要:

这本书试图建立一个相互作用粒子的一致的相对论性量子理论。在书的第一部分“量子电动力学”我们遵循相当传统的方法粒子物理学。从相对性原理、量子测量的基本假设到量子电动力学中的重整化,我们进行了系统的讨论。在第二部分的书“量子理论的粒子”这种传统的做法是重新审查。我们发现狭义相对论的公式应该被修改以考虑粒子间的相互作用。我们还建议用物理“装扮”粒子的语言重新解释量子场论。该公式消除了重正化的需要,为研究量子相互作用系统的动力学和束缚态性质开辟了一条新的途径。发展的理论被应用到现实的物理对象和过程,包括氢原子的能谱,运动不稳定粒子的衰变规律,和相对论电子束的电场。这些结果迫使我们重新审视现代粒子理论的一些核心问题,特别是闵可夫斯基时空统一、量子场和重整化的作用以及所谓的超距作用的不可能性。对这些问题提出了一个新的观点。它可以帮助解决理论物理学的老问题--相对论和量子力学的一致统一。

英文摘要:

This book is an attempt to build a consistent relativistic quantum theory of interacting particles. In the first part of the book "Quantum electrodynamics" we follow rather traditional approach to particle physics. Our discussion proceeds systematically from the principle of relativity and postulates of quantum measurements to the renormalization in quantum electrodynamics. In the second part of the book "Quantum theory of particles" this traditional approach is reexamined. We find that formulas of special relativity should be modified to take into account particle interactions. We also suggest reinterpreting quantum field theory in the language of physical "dressed" particles. This formulation eliminates the need for renormalization and opens up a new way for studying dynamical and bound state properties of quantum interacting systems. The developed theory is applied to realistic physical objects and processes including the energy spectrum of the hydrogen atom, the decay law of moving unstable particles, and the electric field of relativistic electron beams. These results force us to take a fresh look at some core issues of modern particle theories, in particular, the Minkowski space-time unification, the role of quantum fields and renormalization as well as the alleged impossibility of action-at-a-distance. A new perspective on these issues is suggested. It can help to solve the old problem of theoretical physics -- a consistent unification of relativity and quantum mechanics.
