Abstract
This communication concerns the structure of the electromagnetic quant
um vacuum in a disclinated insulator. It is shown that a nonzero vacuu
m energy density appears when the rotational symmetry of a continuous
insulating elastic medium is broken by a disclination. An explicit exp
ression is given for this Casimir energy density in terms of the param
eter describing the disclination.
