Thermal Time and Irreversibility from Non-Commuting Observables in Accelerated Quantum Systems

Temporal ordering becomes physically meaningful when quantum states exhibit KMS thermal structure and detectors couple through non-commuting observables. Relative entropy quantifies irreversibility governed by local temperature in accelerated systems.

Decoherence Scaling Law Opens Practical Path to Detecting the Unruh Effect

Researchers derived a universal law showing Unruh-DeWitt detector decoherence scales as acceleration^(2Δ-1) via Schwinger-Keldysh formalism. Fermionic fields yield 5th-power scaling vs linear for scalars, offering a feasible Unruh effect detection alternative.
