Casimir effect for perfect non-reciprocal conductors: An analytic extension of Casimir's original work — •Stefan Rode, Robert Bennett, and Stefan Yoshi Buhmann — Albert-Ludwigs University of Freiburg, Germany

We present the Casimir effect for boundary conditions involving perfect electromagnetic conductors (PEMCs), which are a class of non-reciprocal materials that interpolate between perfectly electrically conducting and perfect magnetically conducting media. Based on the dyadic Green's tensor of the electromagnetic field between two reciprocal plates, we demonstrate the construction of the corresponding quantity for two perfectly reflecting non-reciprocal plates. We then calculate the Casimir force between two PEMC plates in terms of the parameter that specifies the degree of mixing between electric and magnetic responses. Our results are simple analytic expressions, which can be related to the electric-magnetic duality symmetry of the electromagnetic field.
