Anatomy of Quantum Tunneling

  • Neil TurokEmail author

Abstract

We use complex classical solutions to provide a simple and transparent treatment of quantum tunneling. We show that the imaginary part of the tunneling coordinate may be weakly measured, and that it yields a quantum-anomalous contribution to the classically-conserved momentum of a classical von Neumann “pointer.” Further developments and applications are mentioned. [Editor’s note: for a video of the talk given by Prof. Turok at the Aharonov-80 conference in 2012 at Chapman University, see quantum.chapman.edu/talk-19.]
