Klein-Gordon场II的量子力学:相对论相干态

Quantum Mechanics of Klein-Gordon Fields II: Relativistic Coherent States

A. Mostafazadeh, F. Zamani

摘要:

本文利用第一篇文章中给出的一次量子化Klein-Gordon场的量子力学公式来研究相对论相干态。特别是,我们提供了一个明确的建设的相干态的带电和中性(实)自由克莱因-戈登领域以及带电领域与恒定磁场相互作用。我们的结构是免费的问题与电荷超选择规则,复杂的以前的研究。我们计算与我们的相干态相关的各种物理量,并详细研究它们的经典(非量子)和非相对论极限。

英文摘要:

We use the formulation of the quantum mechanics of first quantized Klein-Gordon fields given in the first of this series of papers to study relativistic coherent states. In particular, we offer an explicit construction of coherent states for both charged and neutral (real) free Klein-Gordon fields as well as for charged fields interacting with a constant magnetic field. Our construction is free from the problems associated with charge-superselection rule that complicated the previous studies. We compute various physical quantities associated with our coherent states and present a detailed investigation of their classical (nonquantum) and nonrelativistic limits.
