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…

Topological optical skyrmion transfer to matter
Chirantan Mitra, Chetan Sriram Madasu, Lucas Gabardos +4
The ability of structured light to mimic exotic topological skyrmion textures, encountered in high-energy physics, cosmology, magnetic materials, and superfluids has recently recei…

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…
