Symmetry breaking states of matter can transmit symmetry breaking to nearby atoms or molecular complexes, perturbing their spectra. We calculate one such effect, involving the “axion electrodynamics” relevant to topological insulators, quantitatively. We provide an operator framework whereby effects of this kind can be analyzed systematically, qualitatively, and discuss possible experimental implications.
Figures for illustration:
(a) Illustration of quantum atmosphere induced by a Chern-Simon surface. The blue layer corresponds to the top surface described by a Chern-Simon term at z = 0. Due to quantum fluctuation, time-reversal symmetry breaking effect will be transmitted to the nearby atom at the distance r from the surface. (b) Feynman diagram involving Chern-Simon vortex.
