Rotational and vibrational decay of diatomic molecules near a surface — •Nicolas Schüler, Omar Jesús Franca Santiago, and Stefan Yoshi Buhmann — Institute of Physics, University of Kassel, Germany

We study the rotational and vibrational motion of chiral diatomic molecules near a dielectric surface [1]. We use macroscopic quantum electrodynamics [2] to obtain the decay rate of the molecule. We determine the critical distances at which retarded (nonretarded) interactions with the surface become dominant, which happens when the distances are much larger (smaller) than the atomic transition wavelengths, respectively. We explore potential links of the rotational and vibrational dynamics with quantum friction.
