Qubit-photon corner states in all dimensions
Adrian E. Feiguin, Juan José García‐Ripoll, Alejandro González-Tudela · Physical Review Research · 2020
This paper shows how a single atom can be used to trap light between mirrors in any dimension, forming what is called a bound-state-in-the-continuum (BIC). The authors use the directional emission appearing in photonic crystal like mediums together with careful design of the mirrors to achieve the desired interference effects.
