Comment on "Heat fluctuations in Brownian transducers".
The results presented in [A. Gomez-Marin and J.M. Sancho, Phys. Rev. E 73, 045101(R) (2006)] are mathematically incomplete and physically faulty. Contrary to their claim, there exists a fluctuation theorem for the heat probability distribution function in Brownian transducers operating between two heat reservoirs. The corresponding large deviation function is determined exactly.
