<p style="text-align: left;">In a significant leap forward for quantum nanophotonics, a team of European and Israeli physicists, introduces a new type of polaritonic cavities and redefines the limits of light confinement. This pioneering work, detailed in a study published today in <a href="https://www.nature.com/articles/s41563-023-01785-w"><em>Nature Materials</em></a><em>, </em>demonstrates an unconventional method to confine photons, overcoming the traditional limitations in nanophotonics.</p>
