Magneto-Electric response functions for simple atomic systems
arXiv:1106.3886 · doi:10.1140/epjd/e2011-20365-y
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/ω^2 whilst at low frequencies it tends to a constant value.
