非绝热效应的出现是由于避免交叉或圆锥形的交叉，自然存在于无场空间或诱导的经典激光场的分子。最近的研究表明，非绝热效应也可以在光腔中产生。在这里，量子化的辐射场混合了原子核和电子的自由度。我们证明了使用腔的量子化场和经典激光场的等效性，就像通常对分子所做的那样。这是证明为纳尔，表现出明显的自然（内在的）避免交叉竞争，避免交叉诱导的领域。此外，在经典激光中，旋转分子表现出光致圆锥交叉（LICI），我们也研究了这些交叉的影响。对于Nal，我们无疑证明了激光诱导的避免交叉和LICl对分子动力学的影响之间的显着差异。
Nonadiabatic effects arise due to avoided crossings or conical intersections that are either present naturally in field-free space or induced by a classical laser field in a molecule. Recently, it was demonstrated that nonadiabatic effects in diatomics can also be created in an optical cavity. Here, the quantized radiation field mixes the nuclear and electronic degrees of freedom. We show the equivalence of using the cavity's quantized field and the classical laser field as usually done for molecules. This is demonstrated for Nal, which exhibits a pronounced natural (intrinsic) avoided crossing that competes with the avoided crossing induced by the field. Furthermore, rotating molecules exhibit light induced conical intersections (LICIs) in classical laser light, and we also investigate the impact of these intersections. For Nal, we undoubtedly demonstrate a significant difference between the impact of the laser-induced avoided crossing and that of the LICl on the dynamics of the molecule.
