}Abstract
We consider a simple atomic two-body bound state system that is overall charge neutral
and placed in a static electric and magnetic field, and calculate the magneto-electric
response function as a function of frequency. This is done from first principles using a
two-particle Hamiltonian for both an harmonic oscillator and Coulomb binding potential. In
the high frequency limit, the response function falls off as
1/ω2 whilst at low frequencies it tends to a constant
value.

Momentum transfer from quantum vacuum to magnetoelectric matter.

This work presents a Lorentz-invariant description of momentum transfer from zero-point quantum fluctuations to matter, controlled by applied electric and magnetic fields, and finds no momentum transfer for homogeneous media, but predicts a very small transfer for a Casimir-type geometry.

The Green-function formalism for the electromagnetic field in a magnetoelectric (ME) medium is constructed as a generalization of conventional Casimir theory and predicts electromagnetic momentum to be extracted from the vacuum field, just analogous to how energy is extracted in the Casimir case.
