Study sheds light on gauge invariance in ultrastrong-coupling cavity quantum electrodynamics
In quantum electrodynamics, the choice of gauge (i.e. specific mathematical formalism used to regulate degrees of freedom) can greatly influence the form of light-matter interactions. Interestingly, however, the “gauge invariance” principle implies that all physical results should be independent fro…

Simulations show a single photon can simultaneously excite two atoms
(Phys.org)—A small team of researchers with affiliations to institutions in Italy, Japan and the U.S. has created a simulation that suggests that it should be possible for a single photon to simultaneously excite two atoms. In their paper published in the open access journal Physical Review Letters,…
