    • Effective screening of medium-assisted van der Waals interactions between embedded particles 

      Fiedler, Johannes; Walter, Michael; Buhmann, Stefan Yoshi (Journal article; Peer reviewed, 2021)
      The effect of an implicit medium on dispersive interactions of particle pairs is discussed, and simple expressions for the correction relative to vacuum are derived. We show that a single point Gauss quadrature leads to ...

    • Monolithic atom interferometry 

      Fiedler, Johannes; Lefmann, Kim; von Klitzing, Wolf; Holst, Bodil (Journal article; Peer reviewed, 2023)
      Atom and, more recently, molecule interferometers are used in fundamental research and industrial applications. Most atom interferometers rely on gratings made from laser beams, which can provide high precision, but cannot ...

    • A novel approach to construct self-assembled 3D MEMS arrays 

      Akhundzada, Sapida; Yang, Xiaohui; Fiedler, Johannes; Käkel, Eireen; Al-Qargholi, Basim; Buhmann, Stefan; Ehresmann, Arno; Hillmer, Hartmut (Journal article; Peer reviewed, 2022)
      The paper presents the design and technological fabrication process of Yin or Yang-shaped, micron-sized electromechanical system (MEMS) elements displaying asymmetric hollow cylinders with two different curvatures of the ...

    • Perspectives on weak interactions in complex materials at different length scales 

      Fiedler, Johannes; Berland, Kristian; Borchert, James; Corkery, Robert; Eisfeld, Alexander; Gelbwaser-Klimovsky, David; Greve, Martin Møller; Holst, Bodil; Jacobs, Karin; Kruger, Matthias; Parsons, Drew F.; Persson, Clas; persselt, martin; Reisinger, Thomas; Scheel, Stefan; Stienkemeier, Frank; Tømterud, Martin; Walter, Michael; Weitz, Ralf Thomas; Zalieckas, Justas (Journal article; Peer reviewed, 2022)
      Nanocomposite materials consist of nanometer-sized quantum objects such as atoms, molecules, voids or nanoparticles embedded in a host material. These quantum objects can be exploited as a super-structure, which can be ...

    • Purcell-induced suppression of superradiance for molecular overlayers on noble atom surfaces 

      Fiedler, Johannes; Berland, Kristian; Buhmann, Stefan Yoshi (Journal article; Peer reviewed, 2022)
      We study the impact of an environment on the electromagnetic responses of a molecule in the presence of a dielectric medium. By applying the dipole–dipole coupling between the molecule’s and the environment’s degrees of ...

    • Realistic mask generation for matter-wave lithography via machine learning 

      Fiedler, Johannes; Palau, Adria Salvador; Osestad, Eivind Kristen; Parviainen, Pekka; Holst, Bodil (Journal article; Peer reviewed, 2023)
      Fast production of large-area patterns is crucial for the established semiconductor industry and enables industrial-scale production of next-generation quantum devices. Metastable atom lithography with binary holography ...
