Photons from the laser can excite electrons in the water molecules into a so-called anti-bonding state. Molecules in this state can adopt one of two distorted shapes, both of which can dissociate into...
Banin and co-workers used quantum dots made of indium arsenide, covered with a nonconducting barrier of hexane dithiol molecules and linked to a conducting gold film. The radius of the nearly spherica...
Nearly all the quantum models of the brain depend on how long the brain can keep quantum coherence. Penrose argues for example, that microtubles – small hollow cylinders that help cells keep the...
Photons are traditionally detected by converting their energy into an electric signal, which destroys the photon in the process. An additional problem in quantum measurements is that if one variable &...

Phillips and his colleagues produced a focused directional output from the Bose-Einstein condensate by firing two laser beams into the condensate. One beam adds energy to the atoms, while the second s...
Both the French-Italian gravity-wave interferometer, called VIRGO, and the LIGO interferometers in the US are designed to detect very weak gravity waves by using lasers to monitor test masses placed a...
Tai Chang Chiang and co-workers at Urbana confined electrons in thin films of silver ranging from 1 monolayer to around 100 monolayers thick. Just as photons resonate back and forth in an optical Fabr...
“Heisenberg is an intelligent man, but a typical German (that is to say a Tacitus).” So wrote Albert Einstein to his Swiss confidant Carl Seelig, in January 1953. Although the quotation do...
Electromagnetically induced transparency relies on interference between different electronic transitions in an atom and has been used to make opaque media transparent at certain wavelengths in the pas...
Normal metals have an equal number of electrons with spin “up” and spin “down”. However, when there are more spins pointing up than down, or vice versa, the metal becomes a fer...
