Electrostatics in a wormhole geometry
Bernard Linet
We determine in closed form the electrostatic potential generated by a point charge at rest in a simple model of static spherically symmetric wormhole. From this, we deduce the ele…
Light propagation around a relativistic vortex flow of dielectric medium
B. Linet
We determine the path of the light around a dielectric vortex described by the relativistic vortex flow of a perfect fluid.
Characteristic hypersurfaces in a relativistic superfluid theory
B. Linet
By discussing the Cauchy problem, we determine the covariant equation of the characteristic hypersurfaces in a relativistic superfluid theory.
Can a self-gravitating thin cosmic string obey the Nambu-Goto dynamics ?
B. Boisseau, C. Charmousis, B. Linet
We assume that a self-gravitating string is locally described by a thin tube of matter represented by a ``smoothed conical metric''. If we impose a specific constraint on the model…
Euclidean scalar and spinor Green's functions in Rindler space
B. Linet
In Rindler space, we consider the Feynman Green's functions associated with either the Fulling-Rindler vacuum or the Minkowski vacuum. In Euclidean field theory, they becomes respe…
