Emergence of an Epsilon-Near-Zero Medium from Microscopic Atomic Principles
L. Ruks, J. Ruostekoski
We demonstrate that an effective near-zero refractive index can emerge from collective light scattering in a discrete atomic lattice, using essentially exact microscopic simulation…

Negative refraction of light in an atomic medium
L. Ruks, K. E. Ballantine, J. Ruostekoski
The quest to manipulate light propagation in ways not possible with natural media has driven the development of artificially structured metamaterials. One of the most striking effe…
