第三类隧穿:量子场论有效非定域性的检验

Tunneling of the 3rd Kind: A Test of the Effective Non-locality of Quantum Field Theory

Simon A. Gardiner, Holger Gies, Joerg Jaeckel, Chris J. Wallace

摘要:

在一个原本局域的量子场论中,将虚量子涨落积分出去,得到一个非局域的有效理论。在这封信中,我们认为第三类隧穿-粒子通过分裂成一对虚粒子穿过势垒,这对虚粒子只有在有限的距离后才重新组合-提供了对这种非定域性的直接测试。我们绘制了一个量子光学装置来测试这种效应,并在一个简单的玩具模型中研究了可观察到的效应。

英文摘要:

Integrating out virtual quantum fluctuations in an originally local quantum field theory results in an effective theory which is non-local. In this Letter we argue that tunneling of the 3rd kind - where particles traverse a barrier by splitting into a pair of virtual particles which recombine only after a finite distance - provides a direct test of this non-locality. We sketch a quantum-optical setup to test this effect, and investigate observable effects in a simple toy model.
