The angulon theory was able to describe non-adiabatic dynamics of iodine molecules in superfluid helium nanodroplets, as observed in experiments of Henrik Stapelfeldt:

Laser-induced rotation of iodine molecules in He-nanodroplets: revivals and breaking-free,
Phys. Rev. Lett. 118, 203203 (2017)
Interestingly, the revival of alignment observed experimentally can be explained as a rotational revival of the angulon quasiparticle.
The theory was developed by Dr. Jan Kaczmarczyk, a postdoctoral fellow in our group.
