Horizon temperature on the real line

Publication date: Available online 27 November 2018Source: Physics Letters BAuthor(s): Michele Arzano, Jerzy Kowalski-GlikmanAbstractWe illustrate the analogue of the Unruh effect for a quantum system on the real line. Our derivation relies solely on basic elements of representation theory of the group of affine transformations without a notion of time or metric. Our result shows that a thermal distribution naturally emerges in connecting quantum states belonging to representations associated to distinct notions of translational symmetry.
