Tunnelling of the 3rd kind : a test of the effective non-locality of quantum field theory.

Gardiner, S.A. and Gies, H. and Jaeckel, J. and Wallace, C.J. (2013) 'Tunnelling of the 3rd kind : a test of the effective non-locality of quantum field theory.', Europhysics letters., 101 (6). p. 61001.

Abstract

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 tunnelling 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.
