The results of their study were released yesterday in the journal Physical Review Letters, published by the American Physical Society. People have studied classical metasurfaces for a long time, says Diego Dalvit, who works in the Condensed Matter and Complex Systems group at the Laboratory s Theoretical Division. But we came up with this new idea, which was to modulate in time and space the optical properties of a quantum metasurface tha
