THE dispersion formula of Kramers and Heisenberg is valid for an atomic system the dimensions of which are small compared with the wave-length of incident light. For very short waves the scattering ...

Nature does not allow us to increase the size of a system without eventually losing coherence. For example, although a coherent laminar flow through a pipe is always linearly stable, increasing the ...

We theoretically demonstrate and experimentally verify such tailored polaritons at the interface of heterostructures. The interface engineering may shed new light on programmable polaritonics, energy ...
