Final report

  
Results in Hungarian
A fényindukált nemadiabatikus hatás szabályozható módon csatolja a molekulák különböző elektronállapotait, és a térintenzitástól függően ez a csatolás erős is lehet a fényindukált kónikus kereszteződések (LICI) közelében. A LICI jelenléte számos statikus és dinamikus nemdiabatikus jelenség forrása. A fény-indukált gyors, nemadiabatikus dinamikát és interferenciahatásokat vizsgáltuk számos kétatomos molekuláris rendszer esetében. Emellett néhány két- és többatomos molekula fény-öltöztetett forgási-rezgési spektruma is tanulmányozásra került. Fókuszáltunk a kvantumfény által kiváltott nemdiabatikus jelenségekre is. Alternatívájaként a molekulák intenzív lézerterekkel történő kölcsönhatásainak, erős fény-anyag csatolás érhető el a molekulák mikro méretű optikai vagy plazmonikus üreg-rezonátorokba történő zárásával is. Az ilyen rendszereket általában fény-öltöztetett vagy polariton állapotokkal írják le, amelyek a teljes „molekula + sugárzási tér” rendszer sajátállapotai. Ebben a megközelítésben számos két- és többatomos rendszer dinamikai, spektroszkópiai és topológiai tulajdonságait vizsgáltuk. Különösen fontos az az általános megállapításunk, hogy a Born-Oppenheimer közelítés érvényét veszítheti kvantum-fény által indukált kónikus kereszteződés hatására, s ez az effektus már többatomos molekulák kétdimenziós modelljében is megjelenik.
Results in English
Light-induced nonadiabaticity couples in a controllable way the different electronic states of the molecule and depending on the field intensity this coupling can be strong in the vicinity of the light-induced conical intersections (LICIs). The presence of a LICI provides a source for numerous statical and dynamical nonadiabatic phenomena. Concerning dynamics and interference effects due to LICIs,we have studied the impact of the LICI on the dissociation dynamics of several diatomic systems. Moreover, we have also investigated the dressed state rovibronic spectra of several diatomic and polyatomic molecules. We have also concentrated on the subject of quantum light-induced nonadiabatic phenomena. It is an alternative to interactions of molecules with intense laser fields, strong light−matter coupling can also be achieved by the confinement of molecules in microscale optical or plasmonic nano-cavities. Such systems are usually described in terms of field-dressed or polariton states, which are the eigenstates of the full “molecule + radiation field” system. In this framework, we have investigated several dynamical, spectroscopic and topological properties of diatomic and polyatomic systems. Of particular importance is our general finding that the Born-Oppenheimer approximation fails in the presence of a LICI which is already present in the two dimensional model.
