    • Axion electrodynamics and the axionic Casimir effect 

      Brevik, Iver Håkon (Peer reviewed; Journal article, 2021)
      A general scheme for axion electrodynamics is given, in which a surrounding medium of constant permittivity and permeability is assumed. Then, as an application, we provide simple numerical estimates for the electromagnetic ...

    • Rotational Curves of the Milky Way Galaxy and Andromeda Galaxy in Light of Vacuum Polarization around Eicheon † 

      Cherkas, Sergey L.; Kalashnikov, Vladimir (Peer reviewed; Journal article, 2023)
      Eicheon properties are discussed. It is shown that the eicheon surface allows setting a boundary condition for the vacuum polarization and obtaining a solution describing the dark matter tail in the Milky Way Galaxy. That ...

    • The Cosmic Causal Mass 

      Bræck, Simen; Grøn, Øyvind; Farup, Ivar (Journal article; Peer reviewed, 2017)
      In order to provide a better understanding of rotating universe models, and in particular the Gödel universe, we discuss the relationship between cosmic rotation and perfect inertial dragging. In this connection, the concept ...

    • Vacuum Polarization Instead of “Dark Matter” in a Galaxy 

      Cherkas, Sergey L.; Kalashnikov, Vladimir (Journal article; Peer reviewed, 2022)
      We considered a vacuum polarization inside a galaxy in the eikonal approximation and found that two possible types of polarization exist. The first type is described by the equation of state p=ρ/3, similar to radiation. ...

    • Æther as an Inevitable Consequence of Quantum Gravity 

      Cherkas, Sergey; Kalashnikov, Vladimir (Peer reviewed; Journal article, 2022)
      The fact that quantum gravity does not admit an invariant vacuum state has far-reaching consequences for all physics. It points out that space could not be empty, and we return to the notion of an æther. Such a concept ...
