Experimental physics

Perhaps dark matter is made of an entirely different kind of particle than the ones physicists have been searching for. New experiments are springing up to look for these ultra-lightweight phantoms.

Long-anticipated experiments that use light to mimic gravity are revealing the distribution of energies, forces and pressures inside a subatomic particle for the first time.

The development of attosecond pulses of light allowed researchers to explore the frame-by-frame movement of electrons.

Physicists finally know where at least some of these high-energy particles come from, which helps make the neutrinos useful for exploring fundamental physics.

By measuring inflated helium nuclei, physicists have challenged our best understanding of the force that binds protons and neutrons.

A novel type of neural network is helping physicists with the daunting challenge of data analysis.

If the electron’s charge wasn’t perfectly round, it could reveal the existence of hidden particles. A new measurement approaches perfection.

Last fall, a team of physicists announced that they had teleported a qubit through a holographic wormhole in a quantum computer. Now another group suggests that’s not quite what happened.

A paper in Nature reports the discovery of a superconductor that operates at room temperatures and near-room pressures. The claim has divided the research community.
