DOI: 10.1103/physreva.98.053808
Abstract: When a two-level system (TLS) is coupled to an electromagnetic resonator, its transition frequency changes in response to the quantum vacuum fluctuations of the electromagnetic field, a phenomenon known as the Lamb shift. Remarkably, by… read more here.

DOI: 10.1103/physrevlett.119.256802
Abstract: We study the shift of the energy levels of electrons on a helium surface due to the coupling to the quantum field of surface vibrations. As in quantum electrodynamics, the coupling is known, and it… read more here.
