5 Deterministic Processes In the previous sections we described the stochastic Markov process. The deterministic processes were described in Chapter 2. It turns out that an arbitrary deterministic process is a Markov process. Both of these types of processes are usually described in different representations, however, they can be unified. Let us consider a process described by a set of dynamic variables x n . The deterministic evolution of the variables is fully described by a set of differential equations: @x n D g n (x1 .

In this case the propagation proceeds according to the deterministic evolution described by the Kronecker delta. 6 Definition of the waiting time distribution in the partially deterministic process. The Liouville-like equation for the PDP is now given by @ p (x, t) D @t @ [g(x)p (x, t)] C @x Z dx 0 [k(xjx 0 )p (x 0, t) k(x 0 jx)p (x, t)] . 110) The first term here describes the deterministic drift, and the second term denotes the stochastic jumps between states. This equation is similar to the Fokker–Planck equation; the jumps, however, do not occur continuously.

106) The Hamiltonian that results from the Lagrangian L0 D L C L add reads " # Z 1 Π2 3 2 2 d r H D Hmol C C 0 c (r A) 2 0 Z Z 1 1 d3 r P ? Π C d3 rjP ? j2 . 107) The transverse polarization consists of contributions of the two molecules, P ? D ? P? 1 C P 2 , and thus the last term can be divided into intramolecular and intermolecular parts: Z Z Z 1 1 1 X 2 d3 rjP ? j2 D d3 r P ? d3 rjP ? P? 108) 1 2 C ξ j . 4 Light–Matter Interaction It can be shown [6] that in the dipole approximation the intermolecular part (the first term on the right-hand side) exactly cancels the interaction between the supraP molecules i< j V(ξi , ξ j ) provided V(ξi , ξ j ) includes only dipole–dipole interaction as well.
