WebAug 3, 2024 · In the book Molecular Physics by Demtroder there is an explanation of the Born-Oppenheimer approximation and the adiabatic approximation in terms of a perturbative series. The Hamiltonian is H 0 + T nuc = H 0 + λ W, where T nuc is the nuclear kinetic energy term. The solutions of H 0 are ϕ m ( r, R) and a general wavefunction is … WebThe so-called Born–Huang ansatz is a fundamental tool in the context of ab-initio molecular dynamics, viz., it allows effectively separating fast and slow degrees of freedom and thus treating electrons and nuclei with different mathematical footings. Here, we consider the use of a Born–Huang-like expansion of the three-dimensional time-dependent …
Webing on the Born-Huang expansion of the full molecular wave function, a majority of approaches that provide a numerically accurate description of the so-called \nona-diabatic" processes require the propagation of a set of many-body nuclear wavepackets on a coupled set of Born-Oppenheimer potential-energy surfaces (BOPESs) [7{14].
