I will introduce macroscopic quantum electrodynamics as a powerful tool
to study this force for arbitrary geometries. As examples, I will
consider a dielectric sphere and a grating, showing how the
position-dependent Casimir-Polder energy influences the scattering of
cold atomic matter waves. In the second part of my talk, I will
discuss two more exotic types of Casimir-Polder interaction. Firstly, I
will show how media violating the Lorentz reciprocity property give rise
to force which are sensitive to violations of charge-parity symmetry.
Secondly, I will discuss how atoms moving parallel to a smooth surface
may experience a quantum friction force.
