• Anisotropic contribution to the van der Waals and the Casimir-Polder energies for CO2 and CH4 molecules near surfaces and thin film 

      Thiyam, Priyadarshini; Parashar, Prachi; Shajesh, K. V.; Persson, Clas; Schaden, Martin; Brevik, Iver Håkon; Parsons, Drew F.; Milton, Kimball A.; Malyi, Oleksandr; Boström, Mathias (Journal article; Peer reviewed, 2015)
      In order to understand why carbon dioxide ( CO 2 ) and methane ( CH 4 ) molecules interact differently with surfaces, we investigate the Casimir-Polder energy of a linearly polarizable CO 2 molecule and an isotropically ...
    • Casimir energies for isorefractive or diaphanous balls 

      Milton, Kimball A.; Brevik, Iver Håkon (Journal article; Peer reviewed, 2018)
      It is known that the Casimir self-energy of a homogeneous dielectric ball is divergent, although a finite self-energy can be extracted through second order in the deviation of the permittivity from the vacuum value. The ...
    • Distance-dependent sign reversal in the Casimir-Lifshitz torque 

      Thiyam, Priyadarshini; Parashar, Prachi; Shajesh, Kuloth Vayalombron; Malyi, Oleksandr; Boström, Mathias; Milton, Kimball A.; Brevik, Iver Håkon; Persson, Clas (Journal article; Peer reviewed, 2018)
      The Casimir-Lifshitz torque between two biaxially polarizable anisotropic planar slabs is shown to exhibit a nontrivial sign reversal in its rotational sense. The critical distance $a_c$ between the slabs that marks this ...
    • Lifshitz interaction can promote ice growth at water-silica interfaces 

      Boström, Mathias; Malyi, Oleksandr; Parashar, Prachi; Shajesh, Kuloth Vayalombron; Thiyam, Priyadarshini; Milton, Kimball A.; Persson, Clas; Parsons, Drew F.; Brevik, Iver Håkon (Journal article; Peer reviewed, 2017)
      At air-water interfaces, the Lifshitz interaction by itself does not promote ice growth. On the contrary, we find that the Lifshitz force promotes the growth of an ice film, up to 1–8 nm thickness, near silica-water ...
    • Presence of negative entropies in Casimir interactions 

      Høye, Johan Skule; Brevik, Iver Håkon; Milton, Kimball A. (Journal article; Peer reviewed, 2016)
      Negative entropy in connection with the Casimir effect at uniform temperature is a phenomenon rooted in the circumstance that one is describing a nonclosed system, or only part of a closed system. In this paper we show ...
    • The reality of Casimir friction 

      Milton, Kimball A.; Høye, Johan Skule; Brevik, Iver Håkon (Journal article; Peer reviewed, 2016)
      For more than 35 years theorists have studied quantum or Casimir friction, which occurs when two smooth bodies move transversely to each other, experiencing a frictional dissipative force due to quantum electromagnetic ...
    • Thermal corrections to the Casimir effect 

      Brevik, Iver Håkon; Ellingsen, Simen Andreas; Milton, Kimball A. (Journal article; Peer reviewed, 2006)
      The Casimir effect, reflecting quantum vacuum fluctuations in the electromagnetic field in a region with material boundaries, has been studied both theoretically and experimentally since 1948. The forces between ...
