Problem Set 5 Assignment 7: For a metal the electron density would be approximated by the ‘fermi sea’, 0 v 2 m h 3 v f v , v f 3 2 0 1/3 m with m the effective mass of the electron. The equilibrium electron density for a charged plasma at temperature T is given by the Boltzmann distribution 0 v 0 m 2 k B T 3/2 exp mv 2 2 k B T Using these equilibrium densities evaluate the first non-zero correction terms for the electron density, n r , t , and electron current density, j r , t . n r , t
