• Fast resolution change in neutral helium atom microscopy 

      Flatabø, Ranveig; Eder, Sabrina Daniela; Ravn, Anders K; Samelin, Bjørn; Greve, Martin Møller; Reisinger, Thomas; Holst, Bodil (Peer reviewed; Journal article, 2018)
      In neutral helium atom microscopy, a beam of atoms is scanned across a surface. Though still in its infancy, neutral helium microscopy has seen a rapid development over the last few years. The inertness and low energy of ...
    • Free-standing, axially-symmetric diffraction gratings for neutral matter-waves: experiments and fabrication 

      Reisinger, Thomas (Doctoral thesis, 2011-10-04)
      Since de Broglie’s famous postulation of the wave-nature of material particles and its subsequent experimental verification, it is known that atoms and molecules behave like waves on a small scale. The investigation of ...
    • Nanostructuring of free-standing, dielectric membranes using electron-beam lithography 

      Grepstad, Jon Olav; Greve, Martin Møller; Reisinger, Thomas; Holst, Bodil (Peer reviewed; Journal article, 2013)
      Nanostructured dielectric membranes are used in several applications ranging from de Broglie matter-wave optical elements to photonic crystals. Precise pattern transfer and high aspect ratio structures are crucial for many ...
    • Neutral atom and molecule focusing using a Fresnel zone plate 

      Reisinger, Thomas; Holst, Bodil (Peer reviewed; Journal article, 2008)
      Focusing of neutral atoms and molecules has several potential applications. The very first microscopy images using helium as an imaging probe were published earlier this year. Another possible application is to study the ...
    • Particle–wave discrimination in Poisson spot experiments 

      Reisinger, Thomas; Bracco, Gianangelo; Holst, Bodil (Peer reviewed; Journal article, 2011)
      Matter–wave interferometry has been used extensively over the last few years to demonstrate the quantum-mechanical wave nature of increasingly larger and more massive particles. We have recently suggested the use of the ...
    • Poisson’s spot with molecules 

      Reisinger, Thomas; Patel, Amil A.; Reingruber, Herbert; Fladischer, Katrin; Ernst, Wolfgang E.; Bracco, Gianangelo; Smith, Henry I.; Holst, Bodil (Peer reviewed; Journal article, 2009)
      In the Poisson-spot experiment, waves emanating from a source are blocked by a circular obstacle. Due to their positive on-axis interference an image of the source the Poisson spot is observed within the geometrical shadow ...
