We use laser-induced rotation of single molecules embedded in superfluid helium nanodroplets to reveal angular momentum dynamics and transfer in a controlled setting, under far-from-equilibrium conditions. As an unexpected result, we observe pronounced oscillations of time-dependent molecular alignment that have no counterpart in gas-phase molecules. Angulon theory reveals that these oscillations originate from the unique rotational structure of molecules in He droplets and quantum-state…

Spatiotemporal rotational dynamics of laser-driven molecules

Abstract. Molecular alignment and orientation by laser fields has attracted significant attention in recent years, mostly due to new capabilities to manipulate the molecular spatial arrangement.

Intermolecular forces and correlations mediated by a phonon bath.

The biangulon quasiparticle is introduced, describing two rotating molecules that align with respect to each other due to the effective attractive interaction mediated by the excitations of the bath, and a diagonalization scheme is introduced that allows the transition from two separated angulons to a biangULon as a function of the distance between the two molecules.



CHAPTER 9:Molecular Impurities Interacting with a Many-particle Environment: From Ultracold Gases to Helium Nanodroplets

In several settings of physics and chemistry one has to deal with molecules interacting with some kind of an external environment, be it a gas, a solution, or a crystal surface. Understanding
