We investigate the electromagnetic response of staggered two-dimensional
materials of the graphene family, including graphene, silicene, germanene, and
stanene, as they are driven through various topological phase transitions using
external fields. Utilizing Kubo formalism, we compute their optical conductivity
tensor taking into account the frequency and wave vector of the electromagnetic
excitations, and study its behavior over the full electronic phase diagram of the
materials. Finally, we study the Casimir effect and the Heat Transfer between
papellel sheets of those materials.
