The phase and the group velocity of light propagating in conventional optical media cannot exceed the speed of light in vacuum. However, in so-called epsilon-near-zero (ENZ) materials, light exhibits ...
A tiny chip on the tip of a fibre-optic cable can passively harness light to perform AI computations, dramatically reducing ...
These jets become elusive the farther back in time astronomers try to look because of the so-called cosmic microwave ...
Quantum mechanics plays a role in the process of photosynthesis. Engineers have long sought efficient ways to convert solar ...
