导频波理论与量子场

Pilot-wave theory and quantum fields

Ward Struyve

摘要:

导频波理论为测量问题提供了可能的解决方案。在这样的理论中,量子系统不仅可以用态矢量来描述,还可以用一些附加变量来描述。这些额外的变量,也被称为beables,可以是粒子的位置,场配置,字符串等,在本文中,我们专注于我们的注意力在导频波理论中,额外的变量是场配置。第一个这样的理论是由玻姆针对自由电磁场提出的。自玻姆以来,类似的导波理论已经被提出用于其他量子领域。本文件的目的是对这些建议进行概述和进一步发展。我们讨论了各种玻色子量子场论,如薛定谔场,自由电磁场,标量量子电动力学和阿贝尔希格斯模型。特别是,我们比较了玻姆和瓦伦蒂尼提出的电磁场的导频波理论,发现它们是等价的。我们进一步讨论了霍兰德和瓦伦提尼提出的费米子场的建议。在霍兰德模型的情况下,我们指出,需要进一步的工作,以表明该模型能够再现标准的量子预测。我们还考虑了一个类似的模型,它似乎不能再现标准的量子预测。在瓦伦提尼的模型中,我们指出了一个似乎难以克服的问题。

英文摘要:

Pilot-wave theories provide possible solutions to the measurement problem. In such theories, quantum systems are not only described by the state vector, but also by some additional variables. These additional variables, also called beables, can be particle positions, field configurations, strings, etc. In this paper we focus our attention on pilot-wave theories in which the additional variables are field configurations. The first such theory was proposed by Bohm for the free electromagnetic field. Since Bohm, similar pilot-wave theories have been proposed for other quantum fields. The purpose of this paper is to present an overview and further development of these proposals. We discuss various bosonic quantum field theories such as the Schroedinger field, the free electromagnetic field, scalar quantum electrodynamics and the Abelian Higgs model. In particular, we compare the pilot-wave theories proposed by Bohm and by Valentini for the electromagnetic field, finding that they are equivalent. We further discuss the proposals for fermionic fields by Holland and Valentini. In the case of Holland's model we indicate that further work is required in order to show that the model is capable of reproducing the standard quantum predictions. We also consider a similar model, which does not seem to reproduce the standard quantum predictions. In the case of Valentini's model we point out a problem that seems hard to overcome.
