per atom enthalpy for heat/flux

Thanks Tim for your reply.
I send one pdf. I want to understand wich enthalpy is correct to use it.

The heat flux from Eapen’s PRL Eq. 3 is derived from fluctuations of energy around the mean (“excess energy”), so to me it makes sense to use this approach for G-K analysis and compute the partial enthalpy for each component. The Eapen and Sarkar papers are both using this definition… I’m not familiar with
Hoheisel’s approach of enthalpy sharing between components.
