Prediction Through Quantum Dynamics Simulations: Photo-excited Cyclobutanone

Datasets contain the input and output files for the Quantics program to run MCTDH and DD-vMCG calculations on cyclobutanone. There are various directories containing the ML-MCTDH calculations on the LVC Hamiltonian and the further directories containing the DD-vMCG calculation and database direct dynamics surfaces. These files can be used together with Quantics to generate the data in the paper Bennett et al (JCP, 160: 174305,2024). The input files are standard ascii files, grouped into directories for the different systems studied. The databases with the points calculated during the direct dynamics simulations are SQLite format with tables for geometries, energies, gradients etc. More details are in the paper. The Quantics program is a mostly Fortran code for running quantum dynamics simulations. It is open source and runs on linux workstations. It is freely available on request to the authors of the paper. For further details of the program see Comp. Phys. Comm., 248:107040–15, 2020.
