UW helps create the largest neutrino detectors in the world

A new era in neutrino physics in the United States is underway, and UW–Madison’s Physical Sciences Laboratory (PSL) in Stoughton is playing a key role. The Long-Baseline Neutrino Facility, home to the $2…

Thin photodetector could increase performance without adding bulk

In today’s increasingly powerful electronics, tiny materials are a must as manufacturers seek to increase performance without adding bulk. Smaller also is better for optoelectronic devices — like camera sensors…

New method allows real-time monitoring of irradiated materials

Technique will enable continuous measurement of damage to materials in high-radiation environments. CAMBRIDGE, Mass. — A new advance on a method developed by MIT researchers could enable continuous, high-precision monitoring…

Unpolarized single-photon generation with true randomness from diamond

The Tohoku University research group of Professor Keiichi Edamatsu and Postdoctoral fellow Naofumi Abe has demonstrated dynamically and statically unpolarized single-photon generation using diamond. This result is expected to play…

OLYMPUS experiment sheds light on structure of protons

Seven-year study indicates two photons, not one, are exchanged in electron-proton interactions. CAMBRIDGE, Mass. — A mystery concerning the structure of protons is a step closer to being solved, thanks to…

Stars align in test supporting “spooky action at a distance”

Physicists address loophole in tests of Bell’s inequality, using 600-year-old starlight. CAMBRIDGE, MA — Quantum entanglement may appear to be closer to science fiction than anything in our physical reality….

UW-Madison astrophysics innovator Lawler wins national award

James Lawler, a University of Wisconsin–Madison professor of physics known for devising innovative techniques to measure the chemical elements in the sun and other stars, has been named the recipient…

CERN experiment reports sixfold improved measurement of the magnetic moment of the antiproton

In a paper published today in the journal Nature Communications, the BASE collaboration at CERN reports the most precise measurement ever made of the magnetic moment of the antiproton, allowing a fundamental comparison between matter and antimatter.

Scientists set traps for atoms with single-particle precision

Atoms, photons, and other quantum particles are often capricious and finicky by nature; very rarely at a standstill, they often collide with others of their kind. But if such particles can be individually corralled and controlled in large numbers, they may be harnessed as quantum bits, or qubits — tiny units of information whose state or orientation can be used to carry out calculations at rates significantly faster than today’s semiconductor-based computer chips.

A marriage made in sunlight: Invention merges solar with liquid battery

Song Jin, a professor of chemistry at the University of Wisconsin–Madison, has a better idea: integrating the solar cell with a large-capacity battery. He and his colleagues have made a single device that eliminates the usual intermediate step of making electricity and, instead, transfers the energy directly to the battery’s electrolyte.
