Unruh Effect Detection via Decoherence

This paper explores an indirect method for detecting the Unruh effect, a fundamental prediction of quantum field theory. The Unruh effect, which posits that an accelerating observer perceives a vacuum as a thermal bath, is notoriously difficult to verify directly. This work proposes using decoherence, the loss of quantum coherence, as a measurable signature of the effect. The extension of the detector model to the electromagnetic field and the potential for observing the effect at lower accelerations are significant contributions, potentially making experimental verification more feasible.
