Question

This equation can be obtained using a quasiparticle ansatz from the more general Kadanoff–Baym equation. (15[1])Codes such (15[1])as CAMB use this equation to study polarization in the CMB, and a common “relaxation time” approximation to one term in this equation named for Bhatnagar, Gross, and Krook (15[1])is used in “lattice” (15[2])simulations (15[1])of this equation. That term in this equation can be treated analytically by closure of the (*) BBGKY (10[2])hierarchy. (10[1])This (10[1])equation is coupled to the Maxwell equations in a self-consistent treatment of plasmas named for Vlasov. (-5[1])Terms of the (10[1])form “one plus-or-minus f” can be included in the collision integral of (-5[1])this equation to account for quantum statistics. Approximating this equation by only including one-particle distribution functions is known as the “molecular chaos assumption.” For 10 points, what eponymous kinetic equation models out-of-equilibrium transport phenomena? ■END■ (10[3])
