Event horizons are tunable factories of quantum entanglement
Louisiana State University physicists have leveraged quantum information theory techniques to reveal a mechanism for amplifying, or "stimulating," the production of entanglement in the Hawking effect in a controlled manner. ...

How world's most precise clock could transform fundamental physics
Einstein's theory of general relativity holds that a massive body like Earth curves space-time, causing time to slow as you approach the object—so a person on top of a mountain ages a tiny bit faster than someone at sea ...

Measuring Einstein's photoelectric effect: The time it takes for an electron to be released
When light hits a material, electrons can be released from this material—the photoelectric effect. Although this effect played a major role in the development of the quantum theory, it still holds a number of secrets: To ...

Using the universe's coldest material to measure the world's tiniest magnetic fields
Magnetometers measure the direction, strength or relative changes of magnetic fields, at a specific point in space and time. Employed in many research areas, magnetometers can help doctors to see the brain through medical ...

A century ago, Australia was ground zero for eclipse-watchers, and helped prove Einstein right
In 1922, Australia was even more remote from the rest of the world than it is today. But when it came to astronomy, that year it was the center of everyone's attention.

Atom laser creates reflective patterns similar to light
Cooled to almost absolute zero, atoms not only move in waves like light but also can be focused into shapes called caustics, similar to the reflecting or refracting patterns light makes on the bottom of a swimming pool or ...

Predicting high temperature Bose-Einstein condensation of excitons
National University of Singapore researchers have predicted that an exotic state of matter known as a Bose-Einstein condensate can exist at relatively high temperatures (around 50 K to 100 K) in systems comprising organic ...
