The principle of detailed balance
WebbThe vibrational quenching of N +2 by He has been measured over the same energy range. The measured excitation and quenching rate constants are found to satisfy the principle of detailed balance, implying no significant role for rotational excitation in the excitation or quenching processes. Webb3.1 Detailed balance Detailed balance is an important property of certain Markov Chains that is widely used in physics and statistics. Definition. Let X 0;X 1;:::be a Markov chain with stationary distribution p. The chain is said to be reversible with respect to p or to satisfy detailed balance with respect to p if p ip ij =p j p ji 8i; j: (1)

Webb4 juni 2015 · p ( x) k ( x, y) = p ( y) k ( y, x) ∀ x, y. Local detailed balance. This is a somewhat different concept which, although related, adds some physical properties over and above just the properties of stochastic processes. If you have detailed balance and the system is physical you have the distribution being the equilibrium distribution so that.
