Direct detection of polar structure formation in helium nanodroplets by beam deflection measurements
John W. Niman, Benjamin S. Kamerin, Lorenz Kranabetter +4
Long-range intermolecular forces are able to steer polar molecules submerged in superfluid helium nanodroplets into highly polar metastable configurations. We demonstrate that the…
Oriented polar molecules trapped in cold helium nanodroplets: Electrostatic deflection, size separation, and charge migration
John W. Niman, Benjamin S. Kamerin, Daniel J. Merthe +2
Helium nanodroplets doped with polar molecules are studied by electrostatic deflection. This broadly applicable method allows even polyatomic molecules to attain sub-Kelvin tempera…
The transparency of graphene and other direct-gap two dimensional materials
Daniel J. Merthe, Vitaly V. Kresin
Graphene and other two-dimensional materials display remarkable optical properties, including a simple light transparency of for light in the visible region. Mos…
Electrostatic deflection of a molecular beam of massive neutral particles: Fully field-oriented polar molecules within superfluid nanodroplets
Daniel J. Merthe, Vitaly V. Kresin
Electric deflection measurements on liquid helium nanodroplets doped with individual polar molecules demonstrate that the cold superfluid matrix enables full orientation of the mol…
Proton transfer in histidine-tryptophan heterodimers embedded in helium droplets
Bruno Bellina, Daniel J. Merthe, Vitaly V. Kresin
We used cold helium droplets as nano-scale reactors to form and ionize, by electron bombardment and charge transfer, aromatic amino acid heterodimers of histidine with tryptophan,…
A Sampling Theorem for Computational Diffraction
Daniel J. Merthe
A major challenge of many diffraction calculations, using some form of the Rayleigh-Sommerfeld formulas, is the integration of a highly oscillatory integrand. Here we derive a pote…
