Modeling Quantum Dynamics with Path Integral Generalized Langevin Equation Thermostats

A post-processing scheme for recovering time correlation properties from thermostatted trajectories in quantum molecular dynamics simulations. The approach, introduced by Venkat Kapil of École Polytechnique Fédérale de Lausanne, yields spectroscopic observables with accuracy comparable to more demanding full path integral techniques. The dataset likely contains simulation results for model and realistic molecular systems.

Use Cases

• Benchmarking spectroscopic observable predictions based on the described post-processing scheme.
• Studying quantum nuclear effects in molecular systems based on the path integral generalized Langevin equation method.
