Casimir-Polder energy landscape: Unipolarizable atom and ring
Niranjan Warnakulasooriya, John Joseph Marchetta, Prachi Parashar +1
The Casimir-Polder interaction energy between a unipolarizable point atom and a unipolarizable dielectric ring has been limited, until now, to the case when the atom is confined on…
Temperature-Distance Relations in Casimir Physics
Mathias Bostrom, A. Gholamhosseinian, J. J. Marchetta +2
The Casimir-Lifshitz force arises from thermal and quantum mechanical fluctuations between classical bodies and becomes significant below the micron scale. We explore temperature-d…
Uniform Asymptotic Approximation Method with Pöschl-Teller Potential
Rui Pan, John Joseph Marchetta, Jamal Saeed +4
In this paper, we study analytical approximate solutions of the second-order homogeneous differential equations with the existence of only two turning points (but without poles), b…
Magnetostatic interaction energy between a point magnet and a ring magnet
Niranjan Warnakulasooriya, Dinuka H. Gallaba, John Joseph Marchetta +3
We find an exact closed-form expression for the magnetostatic interaction energy between a point magnet and a ring magnet in terms of complete elliptic integrals. The exact express…
Geometrical dependence in Casimir-Polder repulsion: Anisotropically polarizable atom and anisotropically polarizable annular dielectric
John Joseph Marchetta, Prachi Parashar, K. V. Shajesh
Casimir-Polder interaction energies between a point anisotropically polarizable atom and an annular dielectric are shown to exhibit localized repulsive long-range forces in specifi…
Geometrical dependence in Casimir-Polder repulsion
John Joseph Marchetta, Prachi Parashar, K. V. Shajesh
Repulsion, induced from quantum vacuum fluctuations, for an anisotropically polarizable atom on the symmetry axis of an anisotropically polarizable annular disc is studied. There e…
