Born huang expansion
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 …

It takes into account diagonal nonadiabatic effects in the electronic Hamiltonian better than the Born–Oppenheimer approximation.
