Abstract

We correct a subtle oversight in Eq.(19) of K. Lorek et al. [Class. Quantum Grav. 32 175003 (2015)] concerning the decay probability of a uniformly accelerated quantum clock. The original expression included unphysical cross-wedge term (γˉK12|\bar{\gamma}_{K 1}|^2) violating the spatial separation of Rindler wedges. We derive the corrected probability using the paper's Rindler conformal coordinates (τ,ξ)(\tau, \xi), retaining only causally consistent thermal terms, and discuss implications for relativistic clock models.
