Schwinger-Unruh-Hawking radiation on manifolds

Abstract

The whole picture of gauge theory is described by manifolds, while the field equation provides only a part (a section) of the manifold. Just as a three-dimensional object is reconstructed from two planar images, a monopole is constructed by combining two solutions. The Schwinger and the Unruh effects and the Hawking radiation are the production of particles out of the ``vacuum''. If the '''vacuum'' on the manifold is properly defined, these phenomena should be described as local phenomena. However, calculations using the field equations have so far resulted in unnatural extrapolations. We present a method for properly defining the ``vacuum'' and explain how to resolve the local particle production on manifolds. By defining the Stokes phenomena on the manifold, the Schwinger effect is naturally accompanied by the Unruh effect. Also, unlike the conventional Unruh effect, calculations on manifolds do not suffer from the entanglement between disconnected wedges.
