We perform on-the-fly non-adiabatic molecular dynamics simulations using the symmetrical quasi-classical (SQC) approach with the recently suggested molecular Tully models: ethylene and fulvene. We attempt to provide benchmarks of the SQC methods using both the square and triangle windowing schemes as well as the recently proposed electronic zero-point-energy correction scheme (the so-called γ correction). We use the quasi-diabatic propagation scheme to directly interface the diabatic SQC…

Quasi-Diabatic Scheme for Non-adiabatic On-the-Fly Simulations.
TLDR
The quasi-diabatic (QD) propagation scheme is used to perform on-the-fly non-adiabatic simulations of the photodynamics of ethylene and demonstrates the correct predictions of competing processes of non-radiative relaxation mechanism through various conical intersections.
A symmetrical quasi-classical windowing model for the molecular dynamics treatment of non-adiabatic processes involving many electronic states.
TLDR
The benefits of the two-state triangle model-seamless treatment of weak-coupling and improved accuracy in all coupling regimes-carry over to the generalized version of SQC, enabling the SQC simulation of electronically non-adiabatic processes involving many more relevant electronic states than was previously practical.
Benchmarking Quasiclassical Mapping Hamiltonian Methods for Simulating Electronically Nonadiabatic Molecular Dynamics.
TLDR
A benchmark comparison of a variety of different quasi-classical mapping Hamiltonian methods for simulating electronically nonadiabatic molecular dynamics finds that LSC with the modied identity operator typically performs better than the Ehrenfest and standard LSC approaches.
Symmetric quasi-classical dynamics with quasi-diabatic propagation scheme.
TLDR
This study opens up the possibility for combining accurate diabatic quantum dynamics methods such as SQC with any adiabatic electronic structure calculations for non-adiabatic on-the-fly propagations.
A novel algorithm for non-adiabatic direct dynamics using variational Gaussian wavepackets.
TLDR
This work presents the first direct dynamics calculations using a novel algorithm, based on the powerful multi-configuration time-dependent Hartree (MCTDH) wavepacket propagation method, that provides a feasible direct dynamics algorithm for the description of this non-adiabatic process.
Direct semiclassical simulation of photochemical processes with semiempirical wave functions
We describe a new method for the simulation of excited state dynamics, based on classical trajectories and surface hopping, with direct semiempirical calculation of the electronic wave functions and
A new symmetrical quasi-classical model for electronically non-adiabatic processes: Application to the case of weak non-adiabatic coupling.
TLDR
Application of the SQC/MM approach to the case of very weak non-adiabatic coupling between the electronic states shows that the new model not only treats the weak coupling case extremely well, but it is also seen to describe the "normal" regime even more accurately than the previous "standard" model.

TLDR
This work indicates that the on-the-fly SQC/MM method is a powerful simulation protocol to deal with the nonadiabatic dynamics of realistic polyatomic systems.

TLDR
The adiabatic version of the MM Hamiltonian is revisits and a modification of the classical EOMs is described that are entirely equivalent to Hamilton's equations but that do not involve the second-derivative couplings are described.
