In a recently published article in the journal Physics Letters B, researchers investigated the propagation of light within a theoretical model known as an elliptic wormhole (EWH), characterized by ...

Towards stable propagation of light in nano-photonic fibers Date: September 19, 2016 Source: Institute for Basic Science Summary: Devices based on light, rather than electrons, could revolutionize ...

Devices based on light, rather than electrons, could revolutionize the speed and security of our future computers. However, one of the major challenges in today's physics is the design of photonic ...

The propagation of light is explained by Maxwell’s equations. Although he worked them out in the 19th century, they are consistent with both relativity and quantum mechanics.

The dark side of light: negative frequency photons The impact of something we thought couldn't exist has now been detected.

The researchers managed to image light propagation with a microscope and saw that it behaved as predicted. Moreover, they witnessed the topology, or mathematical description, in the observed light.

Topological spin textures, spatially organized patterns linked to the intrinsic angular momentum of particles, have proved to be highly advantageous for the development of spintronics and quantum ...

Here we employ the recent concept of gradient index metamaterials to demonstrate a waveguide with asymmetric propagation of light, independent of polarization.
