# Energy Transfer and Joint Diffusion

@article{PajorGyulai2010EnergyTA, title={Energy Transfer and Joint Diffusion}, author={Zsolt Pajor-Gyulai and Domokos Sz{\'a}sz}, journal={Journal of Statistical Physics}, year={2010}, volume={146}, pages={1001-1025} }

A paradigm model is suggested for describing the diffusive limit of trajectories of two Lorentz disks moving in a finite horizon periodic configuration of smooth, strictly convex scatterers and interacting with each other via elastic collisions. For this model the diffusive limit of the two trajectories is a mixture of joint Gaussian laws (analogous behavior is expected for the mechanical model of two Lorentz disks).
