Casimir energy of Sierpinski triangles
K. V. Shajesh, Prachi Parashar, Inés Cavero-Peláez +2
Using scaling arguments and the property of self-similarity we derive the Casimir energies of Sierpinski triangles and Sierpinski rectangles. The Hausdorff-Besicovitch dimension (f…
Inflationary universe in terms of a van der Waals viscous fluid
I. Brevik, E. Elizalde, S. D. Odintsov +1
The inflationary expansion of our early-time universe is considered in terms of the van der Waals equation, as equation of state for the cosmic fluid, where a bulk viscosity contri…
Casimir-Polder energy for axially symmetric systems
K. V. Shajesh, Prachi Parashar, Iver Brevik
We develop a formalism suitable for studying Maxwell's equations in the presence of a medium that is axially symmetric, in particular with respect to Casimir-Polder interaction ene…
Electromagnetic -function sphere
Prachi Parashar, Kimball A. Milton, K. V. Shajesh +1
We develop a formalism to extend our previous work on the electromagnetic -function plates to a spherical surface. The electric () and magnetic () couplings to the sur…
Viscous Cosmology for Early- and Late-Time Universe
Iver Brevik, Øyvind Grøn, Jaume de Haro +2
From a hydrodynamicist's point of view the inclusion of viscosity concepts in the macroscopic theory of the cosmic fluid would appear most natural, as an ideal fluid is after all a…
