Comment on ‘Ideal clocks—a convenient fiction’

We correct a subtle oversight in equation (19) of Lorek et al (2015 Class. Quantum Grav. 32 175003) concerning the decay probability of a uniformly accelerated quantum clock. The original expression included an unphysical cross-wedge term (| γ ¯ K 1 | ²) violating the spatial separation of Rindler wedges. We derive the corrected decay probability using the paper’s Rindler conformal coordinates (τ, ξ), retaining only causally consistent thermal terms, and discuss implications for relativistic clock models.
