Environment-limited transfer of angular momentum in Bose liquids
Alberto Cappellaro, Giacomo Bighin, Igor Cherepanov +1
Impurity motion in a many-body environment has been a central issue in the field of low-temperature physics for decades. In bosonic quantum fluids, the onset of a drag force experi…
A simple model for high rotational excitations of molecules in a superfluid
Igor N. Cherepanov, Giacomo Bighin, Constant A. Schouder +3
We present a simple quantum mechanical model describing excited rotational states of molecules in superfluid helium nanodroplets, as recently studied in non-adiabatic molecular ali…
Femtosecond rotational dynamics of D molecules in superfluid helium nanodroplets
Junjie Qiang, Lianrong Zhou, Peifen Lu +17
Rotational dynamics of D molecules inside helium nanodroplets is induced by a moderately intense femtosecond (fs) pump pulse and measured as a function of time by recording the…
Excited rotational states of molecules in a superfluid
Igor N. Cherepanov, Giacomo Bighin, Constant A. Schouder +6
We combine experimental and theoretical approaches to explore excited rotational states of molecules embedded in helium nanodroplets using CS and I as examples. Laser-induc…
Rotational coherence spectroscopy of molecules in helium nanodroplets: Reconciling the time and the frequency domains
Adam S. Chatterley, Lars Christiansen, Constant A. Schouder +7
Alignment of OCS, CS and I molecules embedded in helium nanodroplets is measured as a function of time following rotational excitation by a non-resonant, comparatively weak…
Far-from-equilibrium dynamics of angular momentum in a quantum many-particle system
Igor N. Cherepanov, Giacomo Bighin, Lars Christiansen +4
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-fro…
Fingerprints of angulon instabilities in the spectra of matrix-isolated molecules
Igor N. Cherepanov, Mikhail Lemeshko
The formation of vortices is usually considered to be the main mechanism of angular momentum disposal in superfluids. Recently, it was predicted that a superfluid can acquire angul…
