(Phys.org)—Researchers have designed a new type of mirror that reflects light in a completely different way than conventional mirrors do. The new mirror, called a chiral meta-mirror, has potential applications for information ...
Raman scattering spectroscopy is a necessary and accurate method to characterize lattice structure and probe electron-photon and electron-phonon interactions. In the quantum realm, electrons at the ground states can be excited ...
A scientist might want to do cartwheels upon making a discovery, but this time the discovery itself relies on cartwheels.
