Ultracold atoms dressed by light simulate gauge theories

Our modern understanding of the physical world is based on gauge theories: mathematical models from theoretical physics that describe the interactions between elementary particles (such as electrons or quarks) and explain ...

Gamma rays reach beyond the limits of light

Researchers have discovered a highly efficient way to produce high energy photon beams. The obtained energy is a billion times higher than the energy of photons in visible light. These high-intensity gamma rays significantly ...

Smaller and cheaper particle accelerators?

Traditionally, particle accelerators have relied on electric fields generated by radio waves to drive electrons and other particles close to the speed of light. But in radio-frequency machines there is an upper limit on the ...

European Gateway experiment will monitor radiation in deep space

The first science experiments that will be hosted on the Gateway, the international research outpost orbiting the moon, have been selected by ESA and NASA. Europe's contribution will monitor radiation to gain a complete understanding ...

New experiments constrain Higgs mass (w/Videos)

(PhysOrg.com) -- The territory where the Higgs boson may be found continues to shrink. The latest analysis of data from the CDF and DZero collider experiments at the U.S. Department of Energy's Fermilab now excludes a significant ...
