Physicists made crystal lattice from polaritons

An international research team produced an analog of a solid-body crystal lattice from hybrid photon-electron quasiparticles — polaritons. In the resulting polariton lattice, certain particles’ energy does not depend on their speed. At the same time, the lattice’s geometry, particle concentration and polarization properties can still be modified. This opens up new perspectives for study of quantum effects and the use of optical computing. Results of the study were published in Physical Review Letters.
