Phys. Rev. 31, 101 (1928) - Note on the Principle of Detailed Balancing

WebbThis chapter treats the thermodynamic equilibrium of gases and radiation. According to the principle of detailed balance (Sect. 1.2), any reaction taking place within a thermal gas is exactly counterbalanced by its inverse reaction. Section 1.3 provides a proof of this principle for the special case of binary collisions. WebbIn Sec. 2.2 we use the principle of detailed balance to evaluate the transition rate constants of the master equa-tion describing minimal models of glass formation. In Sec. 2.3 using a trapping model for the phase point we define these minimal models and derive their associated (master) equations. Sec. 2.4 contains derivations of the
