Can Quantized Vibrational Effects be Obtained from Ehrenfest Mixed Quantum-Classical Dynamics?

An interesting question is whether or not mean-field or “Ehrenfest” mixed quantum-classical dynamics can capture the quantized vibrational features in photoabsorption spectra that result from infrared and Raman-active vibrational transitions. We show that vibrational and electronic absorption spectra can be obtained together within a single Ehrenfest simulation. The electronic transitions show new sidebands that are […]

Chronus Quantum has a Youtube page

We’ve posted a few videos of some interesting electronic dynamics calculated with our new software package Chronus Quantum. A big thanks to our own Joshua Goings for making these. Check out how the electron density is perturbed by on resonant electric fields.
