From rotational decay of diatomic molecules to quantum friction — •Nicolas Schüler, Omar Jesús Franca Santiago, and Stefan Yoshi Buhmann — Institute of Physics, University of Kassel, Germany
We study the rotational motion of diatomic molecules in free space and interacting with the quantum electromagnetic field [1]. Using macroscopic quantum electrodynamics [2], we obtain the rotation-dependent decay rates of the molecule. By analyzing the behavior of the resulting rates at zero and finite temperature, we find a connection between the decelerating rotational dynamics and quantum friction.
