Az előadás rövid összefoglalója:

The exchange of energy between electronic and nuclear motion is the origin of 
non-adiabaticity and plays an important role in many molecular phenomena and 
processes. Conical intersections (CIs) of different electronic potential 
energy surfaces have been intensely investigated and lead to the most 
singular non-adiabaticity. The coupling of light and matter induces conical 
intersections which are termed light-induced conical intersections (LICIs).
During the talk we present the subject of LICIs, discussing the achievements 
made so far [1-3]. In contrast to natural CIs, the properties of which are 
dictated by nature, the properties of their light-induced counterparts are 
controllable by choosing the frequency and intensity (or coupling to the 
cavity) of the external light source. This opens the door to inducing and 
manipulating various kinds of non-adiabatic effects.
Several examples of diatomic and polyatomic molecules are presented covering 
both dynamics and spectroscopy. The computational methods employed are 
discussed as well.
