报告题目：Quantum Atmospherics

报告摘要：By altering the propagation of virtual photons, materials can influence the behavior of objects in their vicinity. They can cause forces on macroscopic bodies, or perturb the spectra of nearby molecular complexes.  I’ll briefly describe some new kinds of forces, but mainly discuss how symmetry breaking states of matter can transmit symmetry breaking effects to spectra.   I’ll discuss a few such effects, which involve the “axion electrodynamics” relevant to topological insulators, quantitatively.  Then I’ll describe an operator framework whereby effects of this kind can be analyzed systematically, qualitatively, and discuss possible experimental implications.
