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.

Feigel effect: Extraction of momentum from vacuum?

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.

Quantum vacuum contribution to the momentum of dielectric media.

A new, Casimir-like, quantum phenomenon is predicted: contribution of vacuum fluctuations to the motion of dielectric liquids in crossed electric and magnetic fields.

Jones and magnetoelectric birefringence of pure substances — A computational study

We present the first investigation of condensed-phase effects on the Jones (and magnetoelectric) birefringence of a set of nondipolar (CCl4 and CS2) and dipolar (nitro- and chloro-benzene) molecules

Quantum electrodynamics of Casimir momentum: Momentum of the quantum vacuum?

The electromagnetic vacuum is known to have energy. It has been recently argued that the quantum vacuum can possess momentum, that adds up to the momentum of matter. This "Casimir momentum" is

Jones birefringence in gases: Ab initio electron correlated results for atoms and linear molecules

The results of an ab initio investigation of the Jones birefringence (JB) of noble gases (He, Ne, Ar, Kr) and of a few linear molecules—both centrosymmetric (H2,N2,C2H2) and dipolar (CO)—carried out

The Quantum Theory of Light

(b) Write out the equations for the time dependence of ρ11, ρ22, ρ12 and ρ21 assuming that a light field interaction V = -μ12Ee iωt + c.c. couples only levels |1> and |2>, and that the excited levels

The possibility that a physical system may possess simultaneously two independent linear birefringences is a consequence of the Jones calculus formulated in 1948. Before this only one linear
