Packets of light and vibration couple to create novel materials and processes
Lots of big things happen at very small scales. A photon is a discrete packet of light with a quantised amount of energy that represents the energy that can be absorbed or emitted when an electron changes energy level. A vibron is a quantum of intramolecular vibration. Intermingling of the two, or coupling of electronic states to molecular vibrations (vibronic coupling) is thought to be critical to many biologically and industrially relevant processes. However, it remains a black box of sorts. ContraVib is identifying general rules of control over vibronic coupling and implementing them in a computational framework. Testing of hypotheses and development of novel vibronic control strategies could lead to improved catalysts and optical materials.
