Modeling laser pulses as -kicks: reevaluating the impulsive limit in molecular rotational dynamics
Volker Karle, Mikhail Lemeshko
The impulsive limit (the "sudden approximation") has been widely employed to describe the interaction between molecules and short, far-off-resonant laser pulses. This approximation…
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…
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…
Effect of a magnetic field on molecule-solvent angular momentum transfer
Wojciech Rzadkowski, Mikhail Lemeshko
Recently it was shown that a molecule rotating in a quantum solvent can be described in terms of the `angulon' quasiparticle [Phys. Rev. Lett. 118, 095301 (2017)]. Here we extend t…
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…
Strongly aligned molecules inside helium droplets in the near-adiabatic regime
Benjamin Shepperson, Adam S. Chatterley, Anders A. Søndergaard +3
Iodine (I) molecules embedded in He nanodroplets are aligned by a 160 ps long laser pulse. The highest degree of alignment, occurring at the peak of the pulse and quantified by…
