Casimir effect around disclinations
arXiv:cond-mat/9505023 · doi:10.1016/0375-9601(95)00524-7
Abstract
This communication concerns the structure of the electromagnetic quantum vacuum in a disclinated insulator. It is shown that a nonzero vacuum energy density appears when the rotational symmetry of a continuous insulating elastic medium is broken by a disclination. An explicit expression is given for this Casimir energy density in terms of the parameter describing the disclination.
