• Dispersion forces in inhomogeneous planarly layered media: A one-dimensional model for effective polarizabilities 

      Fiedler, Johannes; Spallek, Fabian; Thiyam, Priyadarshini; Persson, Clas; Boström, Mathias; Walter, Michael; Buhmann, Stefan Yoshi (Journal article; Peer reviewed, 2019)
      Dispersion forces such as van der Waals forces between two microscopic particles, the Casimir-Polder forces between a particle and a macroscopic object, or the Casimir force between two dielectric objects are well studied ...
    • Effective polarisability models 

      Fiedler, Johannes; Thiyam, Priyadarshini; Kurumbail, Anurag; Burger, Friedrich A.; Walter, Michael; Persson, Clas; Brevik, Iver Håkon; Parsons, Drew F.; Boström, Anders Mathias; Buhmann, Stefan Yoshi (Journal article; Peer reviewed, 2017)
      Theories for the effective polarizability of a small particle in a medium are presented using different levels of approximation: we consider the virtual cavity, real cavity, and the hard-sphere models as well as a continuous ...
    • Ice particles sink below the water surface due to a balance of salt, van der Waals and buoyancy forces 

      Thiyam, Priyadarshini; Fiedler, Johannes; Buhmann, Stefan Yoshi; Persson, Clas; Brevik, Iver Håkon; Boström, Mathias; Parsons, Drew F. (Journal article; Peer reviewed, 2018)
      According to the classical Archimedes’ principle, ice floats in water and has a fraction of its volume above the water surface. However, for very small ice particles, other competing forces such as van der Waals forces due ...
    • Orientational dependence of the van der Waals interactions for finite-sized particles 

      Fiedler, Johannes; Persson, Clas; Boström, Mathias; Buhmann, Stefan Yoshi (Journal article, 2018)
      Dispersion forces, especially van der Waals forces as interactions between neutral and polarizable particles act at small distances between two objects. Their theoretical origin lies in the electromagnetic interaction ...
    • Self-preserving ice layers on CO2 clathrate particles: Implications for Enceladus, Pluto, and similar ocean worlds 

      Boström, Mathias; Esteso, Victoria; Fiedler, Johannes; Brevik, Iver Håkon; Persson, Clas; Buhmann, Stefan Yoshi; Carretero-Palacios, Sol; Parsons, Drew F.; Corkery, Robert W. (Peer reviewed; Journal article, 2021)
      Context. Gas hydrates can be stabilised outside their window of thermodynamic stability by the formation of an ice layer – a phenomenon termed self-preservation. This can lead to a positive buoyancy for clathrate particles ...
