    • 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 ...

    • 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 ...

    • Effect of excess charge carriers and fluid medium on the magnitude and sign of the Casimir-Lifshitz torque 

      Thiyam, Priyadarshini; Parashar, Prachi; Shajesh, Kuloth Vayalombron; Malyi, Oleksandr; Boström, Mathias; Milton, K. A.; Brevik, Iver Håkon; Forsman, Jan; Persson, Clas (Journal article; Peer reviewed, 2019)
      Last year, we reported a perturbative theory of the Casimir-Lifshitz torque between planar biaxially anisotropic materials in the retarded limit [Thiyam et al., Phys. Rev. Lett. 120, 131601 (2018)], which is applied here ...

    • Fluid sensitive nanoscale switching with quantum levitation controlled by a-Sn/b-Sn phase transition 

      Boström, Anders Mathias; Dou, Maofeng; Malyi, Oleksandr; Parashar, Prachi; Parsons, Drew F.; Brevik, Iver Håkon; Persson, Clas (Journal article, 2018)
      We analyze the Lifshitz pressure between silica and tin separated by a liquid mixture of bromobenzene and chlorobenzene. We show that the phase transition from semimetallic α−Sn to metallic β−Sn can switch Lifshitz forces ...

    • 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 ...

    • The influence of Lifshitz forces and gas on premelting of ice within porous materials 

      Boström, Mathias; Malyi, Oleksandr; Thiyam, Priyadarshini; Berland, Kristian; Brevik, Iver Håkon; Persson, Clas; Parsons, Drew F. (Journal article; Peer reviewed, 2016)
      Premelting of ice within pores in earth materials is shown to depend on the presence of vapor layers. For thick vapor layers between ice and pore surfaces, a nanosized water sheet can be formed due to repulsive Lifshitz ...
