Exactly solvable 1D model explains the low-energy vibrational level structure of protonated methane
Jonathan I. Rawlinson, Csaba Fábri, Attila G. Császár
A new one-dimensional model is proposed for the low-energy vibrational quantum dynamics of CH5+ based on the motion of an effective particle confined to a 60-vertex graph …

Born-Oppenheimer approximation in optical cavities: from success to breakdown
Csaba Fábri, Gábor J. Halász, Lorenz S. Cederbaum +1
The coupling of a molecule and a cavity induces non-adiabaticity in the molecule which makes the description of its dynamics complicated. For polyatomic molecules, reduced-dimensio…

Striking light-induced nonadiabatic fingerprint in the low-energy vibronic spectra of polyatomic molecules
Csaba Fábri, Benjamin Lasorne, Gábor J. Halász +2
Nonadiabaticity, i.e., the effect of mixing electronic states by nuclear motion, is a central phenomenon in molecular science. The strongest nonadiabatic effects arise due to the p…
