Electrons and how they interact with electromagnetic fields are important in our understanding of chemistry and physics. In the classical view, the energy of an electron orbiting an atomic nucleus is larger for orbits further from the nucleus of an atom. However, quantum mechanical effects force electrons to take on discrete positions in orbitals. Th… WebbLasing action from an optically pumped bound state in the continuum cavity is demonstrated, of both fundamental interest and with applications from optical trapping to biological sensing and quantum information.
