Casimir forces in a plasma: possible connections to Yukawa potentials
Ninham, Barry W.; Boström, Mathias; Persson, Clas; Brevik, Iver Håkon; Buhmann, Stefan Yoshi; Sernelius, Bo. E. (Journal article; Peer reviewed, 2014)We present theoretical and numerical results for the screened Casimir effect between perfect metal surfaces in a plasma. We show how the Casimir effect in an electron-positron plasma can provide an important contribution ... -
Equivalence of Electromagnetic Fluctuation and Nuclear (Yukawa) Forces: the π<inf>0</inf> Meson, its Mass and Lifetime
Ninham, Barry W.; Brevik, Iver Håkon; Boström, Mathias (Peer reviewed; Journal article, 2023)It is shown how Maxwell’s equations for the electromagnetic field with Planck quantisation of allowed modes appears to provide a semiclassical account of nuclear interactions. The mesons emerge as plasmons, collective ... -
A Role for Bose-Einstein Condensation in Astrophysics
Ninham, Barry W.; Brevik, Iver Håkon; Malyi, Oleksandr I.; Boström, Mathias (Peer reviewed; Journal article, 2023)We revive a 60-year-old idea that might explain a remarkable new observation of a periodic low-frequency radio emission from a source at galactic distances (GLEAM-X J162759.5-523504.3). It derives from the observation that ...
