A high or low Kubo number determines whether this process occurs in the quasilinear or percolative regime.
A high or low Kubo number determines whether this process occurs in the quasilinear or percolative regime. A semi-empirical model equates the coefficient of this process in plasmas to k T over 16 times electron charge times magnetic field strength. Kinetic theory relates the coefficient describing this to the Boltzmann constant times temperature times the mobility in the (*) EinsteinSmoluchowski relation. If its coefficient is constant, the PDE named for this process reduces to the heat equation. Thermal conduction occurs due to phonon vibration or electrons undergoing this process. The flux for this process is proportional to the gradient of concentrations in Fick's first law. For 10 points, name this process in which substances move from regions of high concentration to low concentration.
