2 Photon Quantum Interference In A Paint Drop

Light is scattered within a drop of paint so frequently that it would seem impossible to demonstrate quantum effects. But despite the thousands of possible paths the light can take, like a water molecule in a waterfall, researchers of the University of Twente have demonstrated that there are only two exits. Depending on the light pattern that enters the paint, two photons always come out through the same exit, or through different ones, almost as though they avoid each other. [Read More]

New Tunneling State Of Water Molecules Found

Unmatched by any known gas, liquid or solid states, unique and unexpected behavior of water molecules under extreme confinement has been revealed by neutron scattering and computational modeling. Oak Ridge National Laboratory researchers have reported a new tunneling state of water molecules confined in hexagonal ultra-small channels, 5 angstrom across, of the mineral beryl. An angstrom is 1/10-billionth of a meter, and individual atoms are typically about 1 angstrom in diameter. [Read More]

Asymmetric Scattering in Superconductor Dopants

Recently scientists have uncovered materials that can be converted from magnetic insulators or metals into Superconductors, capable of carrying electrical current with no energy loss. It is an extremely promising concept for zero-resistance electronics, energy-storage and transmission systems. Currently, in addition to keeping the materials very cold, a major step to achieving superconductivity is to substitute a different kind of atom into some positions of the “parent” material’s crystal framework.
