Research summary
The paper solves work statistics for a d-level system repeatedly measured in its instantaneous energy basis. It gives a necessary and sufficient class-wise detailed-fluctuation criterion controlled by the antisymmetric part of the composite transfer matrix, proving the fluctuation relation in arbitrary dimension and explaining why symmetric detailed balance is special at dimension two.
