Finite lattice kinetic equations for bosons, fermions, and discrete NLS
Jani Lukkarinen, Sakari Pirnes, Aleksis Vuoksenmaa
We introduce and study finite lattice kinetic equations for bosons, fermions, and discrete NLS. For each model this closed evolution equation provides an approximate description fo…
