In Ref. 1, a theory of the interaction of a particle with an electromagnetic (EM) wave in a plasma based on the quantum Klein–Gordon equation was presented. In this Comment, we show that the basic results of Ref. 1 are recovered by a simple classical calculation, and we add remarks on the (un)suitability of the proposed mechanism for particle energization in both laser and astrophysical plasmas.

Abstract
In Ref. 1, a theory of the interaction of a particle with an electromagnetic (EM) wave in a plasma based on the quantum Klein–Gordon equation was presented. In this Comment, we show that the basic results of Ref. 1 are recovered by a simple classical calculation, and we add remarks on the (un)suitability of the proposed mechanism for particle energization in both laser and astrophysical plasmas.File in questo prodotto:
