Landau's kinetic equation

Landau's kinetic equation describes how the distribution of quasiparticles—interacting electrons in a metal—evolves over time and space. It accounts for their velocities, energies, and interactions, acting as a bridge between microscopic quantum behavior and macroscopic properties like electrical conductivity. The equation considers external disturbances and collisions, enabling understanding of how energy and momentum flow within the material. Essentially, it provides a mathematical framework to predict how the collective behavior of electrons responds to changes, helping scientists analyze phenomena in quantum liquids and strongly interacting electron systems.
