Vacuum energy density and pressure near a soft wall

Abstract: Perfectly conducting boundaries, and their Dirichlet counterparts for quantum scalar fields, predict nonintegrable energy densities. A more realistic model with a finite ultraviolet cutoff yields two inconsistent values for the force on a curved or edged boundary (the "pressure anomaly"). A still more realistic, but still easily calculable, model replaces the hard wall by a power-law potential; because it involves no a posteriori modification of the formulas calculated from the theory, this model should be ano… Show more

“…In the present paper, inspired by the remarkable results of Ref. [24], we generalize our considerations [25][26][27][28] of the local stress tensor in one-dimensional geometries to the electromagnetic case, in which the role of the potential is played by the permittivity. More precisely, the deviation of the permittivity from its vacuum value will be referred to as the potential in this paper.…”
