A proposed device would extend a quantum entanglement scheme previously demonstrated for visible photons into the microwave regime, where it could boost radar performance.
A powerful laser beam separates into many smaller filaments that undergo a phase transition similar to fluid percolating through a porous material.
Researchers generated an electron beam with very high orbital angular momentum—potentially good for atomic-scale images of the magnetism in materials.
An array of nanometer-sized aluminum pyramids acts as a directional antenna for light, and the direction depends on wavelength.
The polarization of an intense laser beam can theoretically be controlled by mixing it with a second beam in a plasma.
