Dissipation in a System Driven by Two Different Thermostats

In an effort to understand phase segregation of polymers driven by activity, i.e., when some of the monomers are driven by an active local energy consuming process, modeled as different monomers interacting with different thermostats, we ask the question: why in such a non-equilibrium system is the average kinetic energy of the monomers not related to the temperature in the usual way via equipartition of energy? This effect turns out to be entirely due to inertia, and to the fact that the dynamics is not completely overdamped.
