Quantum fluctuations of massless scalar fields represented by quantum fluctuations of the quasiparticle vacuum in a zero-temperature dilute Bose-Einstein condensate may well provide the firstâ€¦ (More)

The Casimir force due to thermal fluctuations (or pseudo-Casimir force) was recently calculated for the perfect Bose gas in the slab geometry for various boundary conditions. The Casimir pressure dueâ€¦ (More)

Perfect magnetic conductor (PMC) boundary conditions are dual to the more familiar perfect electric conductor (PEC) conditions and can be viewed as the electromagnetic analog of the boundaryâ€¦ (More)

We study the Casimir piston for massless scalar fields obeying Dirichlet boundary conditions in a three dimensional cavity with sides of arbitrary lengths a, b and c where a is the plate separation.â€¦ (More)

Weyl gravity has been advanced in the recent past as an alternative to General Relativity (GR). The theory has had some success in fitting galactic rotation curves without the need for copiousâ€¦ (More)

We show that it is not possible in the absence of dark matter to construct a four-dimensional metric that explains galactic observations. In particular, by working with an effective potential it isâ€¦ (More)

The trajectory design strategy for the magnetospheric multiscale mission (MMS) involves obtaining a reference path that traverses certain regions of the Earth's magnetosphere. Relative to thisâ€¦ (More)

We study the Casimir effect in the presence of an extra dimension compactified on a circle of radius R (M 4 Ã— S 1 spacetime). Our starting point is the Kaluza Klein decomposition of the 5D Maxwellâ€¦ (More)

Recently, it has been pointed out that dimensionless actions in four dimensional curved spacetime possess a symmetry which goes beyond scale invariance but is smaller than full Weyl invariance. Thisâ€¦ (More)
