Ultracold atoms point toward magnetic behavior
2017/10/2
The researchers found that applying a strong magnetic field to these ultracold atoms caused them to line up in an alternating pattern and lean away from each other. The behavior, which researchers cal...
1 billion suns:World’s brightest laser sparks new behavior in light
1 billion suns World’s brightest laser sparks in light
2017/6/26
By focusing laser light to a brightness 1 billion times greater than the surface of the sun — the brightest light ever produced on Earth — the physicists have observed changes in a vision-enabling int...

From flocks of starlings to schools of fish, nature is full of intricate dynamics that emerge from the collective behavior of individuals. In recent years, interest has grown in trying to capture simi...
Infrared behavior of graviton-graviton scattering
General theory of relativity quantum efficiency high energy scattering cycle amplitude
2014/12/22
The quantum effective theory of general relativity, independent of the eventual full theory at high energy, expresses graviton-graviton scattering at one loop order O E4 with only one para...
