DESCRIPTION:Summary \n\nUNRUH PHENOMENA AND THERMALIZATION FOR QUDIT DETECT
 ORS\n\nQuantum-Nano Centre\, 200 University Ave West\, Room QNC 1201 Water
 loo\,\nON CA N2L 3G1\n\nThe Unruh effect is the flat space analogue to Haw
 king radiation\,\ndescribing how an observer in flat spacetime perceives t
 he quantum\nvacuum state to be in a thermal state when moving along a cons
 tantly\naccelerated trajectory. This effect is often described operational
 ly\nusing the qubit-based Unruh-DeWitt detector.\n\nWe study Unruh phenome
 na for more general qudit detectors coupled to a\nquantized scalar field\,
  noting the limitations to the utility of the\ndetailed balance condition 
 as an indicator for Unruh thermality of\nhigher-dimensional qudit detector
  models. We illustrate these\nlimitations using two types of qutrit detect
 or models based on the\nspin-1 representations of SU(2) and the non-Hermit
 ian generalization\nof the Pauli observables (the Heisenberg-Weyl operator
 s).\n\n[2309.04598] Unruh phenomena and thermalization for qudit detectors
