Observing the topological magnetoelectric effect in classical and quantum electrodynamics

Whenever new states of matter are discovered, or a new energy window is
opened, there is a need and interest to look for new physics. Phases of
matter described by topological order have attracted such attention. On the
one hand they seem promising for applications such as quantum computation or
spintronics and, on the other, they may shed some lights on axion physics,
or on possible magnetic-monopole-like behaviour of certain materials, or on
a novel kind of light-matter interaction. In this talk I will present some
results regarding the electromagnetic response of topological insulators
(TI), Weyl semimetals and chiral metamaterials in configurations that are
highly sensitive to the boundary conditions. In all the cases commented,
minute, yet observable topological magnetoelectric effects are predicted.
Special attention will be paid to the case of systems comprised of a TI and
a quantum dot (QD), both immersed in an external magnetic field. The quantum
mechanical interaction is such that a novel topological entanglement between
the states of the QD and those of the plasmons induced at the TI's surface
is found.
