Microscopic Dynamics of Plasmas and Chaos discusses the resonant wave-particle interplay in plasmas, offers the instruments for chaotic Hamiltonian dynamics, and describes a turbulent macroscopic procedure throughout the chaotic classical mechanics of the corresponding N-body challenge. The booklet starts off with the basics of N-body dynamics, by way of a statistical description of wave-particle interactions.

The implicit dependence then becomes obvious, as we will then have a corresponding equation to that of Eq. (88) for approximate wave functions. In the following derivations, we will use the notation (101) E = = E E E Microscopic Theory of Nonlinear Optics 37 The first-order derivative of the energy is (102) d E E dE = E E E E + E E E which is the analogue of Eq. (89) for approximate wave functions. We have already concluded that the first term vanishes for variational wave functions fulfilling the Hellmann–Feynman theorem [25, 44] and we will in the following only consider this case.

The electronic Hamiltonian is given as (81) ˆ el R r = − H 2 2me 2 i − i e2 4 0 i Z e2 + ri 4 0 i>j 1 rij We note that, in contrast to above, the nuclear repulsion is often included as an additional repulsive potential in the electronic Hamiltonian and thus in the electronic energy. From the solutions of the electronic Schrödinger equation, we obtain the potential that governs the nuclear motions, and the Scrödinger equation for the nuclei can then be solved for the potential provided by the electrons (82) ˆ Knuc R H nuc Kk R = Kk nuc Kk R where K k is the total vibronic energy and Knuck R is the kth vibrational wave function for the K th electronic state.

Carried out to yet a higher order in the perturbation, we will be able to obtain an expression for the three-photon absorption matrix element. The third-order amplitude, taken from Eq. (40), is (78) 3 df t = 1 3 1 ×F t 2 3 mn f0 − f ˆ n n ˆ m m ˆ 0 E 1E 2E n0 − 2 − 3 m0 − 3 1− 2− 3 3 Microscopic Theory of Nonlinear Optics 27 Table 2.
