A new publication from Guido Pupillo‘s team, in collaboration with us, just appeared in the asap section of ACS Photonics. It shows that, intrinsic surface plasmon-phonon polaritons in a metallic crystal, resulting from hybridized plasmons-phonons modes coupled to photonic degrees of freedom, offer a unique opportunity to control the material properties of the crystal, without the use of an external resonator. More details in the publications page.
