Critical Landau velocity in helium nanodroplets

Marcel Drabbels, Evgeniy Loginov, Nils Benedict Brauer, Alberto Hernando de Castro

The best-known property of superfluid helium is the vanishing viscosity that objects experience while moving through the liquid with speeds below the so-called critical Landau velocity. This critical velocity is generally considered a macroscopic property ...

Mid-Infrared Spectroscopy of Molecular Ions in Helium Nanodroplets

Marcel Drabbels, Nils Benedict Brauer, Xiaohang Zhang

High resolution IR spectra of aniline, styrene and 1,1-diphenylethylene cations embedded in superfluid helium nanodroplets have been recorded in the 300-1700 cm-1 range using the free-electron laser FELIX as radiation source. Comparison of the spectra with ...

Hybrid polymer microlens arrays with high numerical apertures fabricated using simple ink-jet printing technique

Vahid Fakhfouri, Dmitri Boiko, Jürgen Brugger, Edoardo Charbon, Nils Benedict Brauer, Joo Yeon Kim

Microlens arrays fabricated by a direct ink-jet printing of UV-curable hybrid polymer are reported. A periodic pattern of polymer drops was ink-jet printed on the surface-treated glass substrate and cured in the UV-light. Using this simple technique, we de ...

Electronic Spectroscopy of Aniline Ions Embedded in Helium Nanodroplets

Marcel Drabbels, Nils Benedict Brauer, Xiaohang Zhang

Excitation spectra of the and transitions of aniline cations embedded in helium nanodroplets are reported. The spectra are characterized by broad asymmetric resonances that consist of an intrinsically broadened zero-phonon line which partially overlaps wit ...

IR spectroscopy of molecular ions by nonthermal ion ejection from helium nanodroplets

Marcel Drabbels, Nils Benedict Brauer

Infrared spectroscopy provides a means to determine the intrinsic geometrical structures of molecules. Here we present a novel spectroscopic method that uses superfluid helium nanodroplets to record IR spectra of cold molecular ions, in this particular cas ...
