Gravitational wave induced perturbation of atomic levels — •Falk Adamietz1,2, Friedemann Queisser1,2, and Ralf Schützhold1,2 — 1Helmholz-Zentrum Dresden-Rossendorf — 2Technische Universität Dresden
Motivated by partly controversial results in the literature and recent studies regarding the detection of gravitational waves with atoms instead of photons (as in LIGO), we study the response of atomic levels to gravitational waves. For slow gravitational waves, we may employ lowest-order stationary perturbation theory. We find that the perturbation Hamiltonian consists both of a kinetic and a potential correction term and explicitly evaluate their matrix elements.
