Quantum field aspect of Unruh problem

TL;DR

This paper demonstrates that quantizing Unruh modes in Minkowski spacetime is impossible, challenging the existence of the Unruh effect by showing it would require boundary conditions altering spacetime topology and symmetry.

Contribution

It provides a novel analysis using both conventional and algebraic quantum field theory approaches to disprove the quantization of Unruh modes and the resulting Unruh effect.

Findings

Quantization of Unruh modes in Minkowski spacetime is impossible.

Imposing boundary conditions alters spacetime topology and symmetry.

The Unruh effect does not exist under these conditions.

Abstract

It is shown using both conventional and algebraic approach to quantum field theory that it is impossible to perform quantization on Unruh modes in Minkowski spacetime. Such quantization implies setting boundary condition for the quantum field operator which changes topological properties and symmetry group of spacetime and leads to field theory in two disconnected left and right Rindler spacetimes. It means that "Unruh effect" does not exist.
