Query: Dynamical contribution to the heat conductivity in stochastic energy
  exchanges of locally confined gases   We present a systematic computation of the heat conductivity of the Markov
jump process modeling the energy exchanges in an array of locally confined hard
spheres at the conduction threshold. Based on a variational formula [Sasada M.
2016, {\it Thermal conductivity for stochastic energy exchange models},
arXiv:1611.08866], explicit upper bounds on the conductivity are derived, which
exhibit a rapid power-law convergence towards an asymptotic value. We thereby
conclude that the ratio of the heat conductivity to the energy exchange
frequency deviates from its static contribution by a small negative correction,
its dynamic contribution, evaluated to be $-0.000\,373$ in dimensionless units.
This prediction is corroborated by kinetic Monte Carlo simulations which were
substantially improved compared to earlier results.
