The calculation of the potential of mean force, AF(z), along the reaction coordinate z, requires statistical sampling by Monte Carlo or molecular dynamics simulations that incorporate nuclear quantum effects employing an adequate potential energy function. In our approach, we use combined QM/MM methods to describe the potential energy function and Feynman path integral approaches to model nuclear quantum effects.

The special case of equation (7.45) with P x) = Q x) — 0 and 5(x) equal to a positive constant, n2 (the choice of n2 as the constant ensures that it is positive quantity for any real value for n), gives rise to equation (7.46) for simple harmonic motion, the solution of which can be used to model nuclear motion in molecules ...

An example gathering some of the problems encountered in the analytical benchmarks is the PSACOIN Tevel E model. Nuclear Energy Agency (1989). As an optional element for the participants, a sensitivity study of the Level-E geosphere transport model was requested. Here Faciha and TUC provided results.

For the time being, however, the microscopic theoretical framework for modeling nuclear structure and reactions is mainly quantum mechanics. The most common models are the shell model and its truncated approximations (e.g., IBM), the mean-field theories (like the... 

The Chebyshev expansion method [430] is applied to the propagation of the nuclear wavepacket subject to the above Hamiltonian for both the two-and three-state models. Nuclear wavefimctions, the potential functions, the matrix to represent the first and second nuclear derivatives arising from T of Eq. (6.70) are all expressed in the sine discrete variable representation (sinc-DVR) [92]. The time length for one-step integration of nuclear wavepacket is set to 0.02 fs. The 1200 DVR grid points are employed within a range from —3 to 14 Bohrs. For a practical reason, the potential function is cut off in the range shorter than 1.2 Bohrs.
