Slowly divergent drift in the field-driven Lorentz gas
Slowly divergent drift in the field-driven Lorentz gas
The dynamics of a point charged particle that moves in a medium of elastic scatterers and is driven by a uniform external electric field is investigated. Using rudimentary approaches, we reproduce, in one dimension, the known results that the typical speed grows with time as ${t}^{1/3}$ and that the leading …
