Objects of maximum electromagnetic chirality
We introduce a definition of the electromagnetic chirality of an object and show that it has an
upper bound. Reciprocal objects attain the upper bound if and only if they are transparent for …

Effect of spin excitations with simultaneous magnetic-and electric-dipole character on the static magnetoelectric properties of multiferroic materials
We derive a sum rule to demonstrate that the static magnetoelectric (ME) effect is governed
by optical transitions that are simultaneously excited by the electric and magnetic …
