The Rotating Quantum Vacuum
Paul C. W. Davies, Tevian Dray, Corinne A. Manogue
TL;DR
This paper investigates how rotating particle detectors respond in various bounded spacetimes, challenging the common belief that detectors do not respond in their vacuum state, with implications for thermodynamics.
Contribution
It derives conditions for detector responses in rotating frames across different spacetimes, providing new insights into quantum field theory in curved backgrounds.
Findings
Detectors can respond in certain bounded spacetimes under rotation.
Potential violations of the second law of thermodynamics are discussed.
Conditions for detector response depend on spacetime geometry and motion.
Abstract
We derive conditions for rotating particle detectors to respond in a variety of bounded spacetimes and compare the results with the folklore that particle detectors do not respond in the vacuum state appropriate to their motion. Applications involving possible violations of the second law of thermodynamics are briefly addressed.
