Welcome to coolvib’s documentation!

coolvib is a python package that calculates quantities related to electronic friction acting on adsorbate atoms and molecules on metal surfaces. This friction is induced by non-adiabatic coupling between electronic and nuclear motion. Such coupling mediates energy loss of adsorbate vibrations and induces vibrational cooling - therefore the name coolvib.
