DESCRIPTION:The Unruh effect is the flat space analogue to Hawking radiation\, describing how an observer in flat spacetime perceives the quantum vacuum state to be in a thermal state when moving along a constantly accelerated trajectory. This effect is often described operationally using the qubit-based Unruh-DeWitt detector.\nWe study Unruh phenomena for more general qudit detectors coupled to a quantized scalar field\, noting the limitations to the utility of the detailed balance condition as an indicator for Unruh thermality of higher-dimensional qudit detector models. We illustrate these limitations using two types of qutrit detector models based on the spin-1 representations of SU(2) and the non-Hermitian generalization of the Pauli observables (the Heisenberg-Weyl operators).\n[2309.04598] Unruh phenomena and thermalization for qudit detectors (arxiv.org) https://arxiv.org/abs/2309.04598
