Dark matter particles could be mediators of the interaction between electrons and atomic nuclei, as shown by a study conducted by junior group leader, Dr. Konstantin Gaul, Dr. Lei Cong, and Professor ...

Chemistry textbooks explain how reactions start and end, but they rarely show what happens in between. Seeing these hidden moments matters because chemistry is ultimately governed by quantum rules. By ...

The temperature of elementary particles has been observed in the radioactive glow following the collision of two neutron stars and the birth of a black hole. This has, for the first time, made it ...

Most clocks, from wristwatches to the systems that run GPS and the internet, work by tracking regular, repeating motions. To build a clock, you need something that ticks in a perfectly repeatable way.

When scientists fire beams of electrons at atomic nuclei, the resulting scattering patterns usually behave exactly as theory predicts. It’s one of the great strengths of modern nuclear physics. This ...

I first learned of this area of research as a graduate student in physical chemistry. My doctoral adviser's group had a project dedicated to studying chemical reactions with attosecond pulses. Before ...

Whether in solar cells or in the human eye: whenever certain molecules absorb light, the electrons within them shift from their ground state into a higher energy, excited state. This results in the ...

A researcher stands behind a metal pipe covered with electrical cords and gauges. A researcher works on a device at the Facility for Rare Isotope Beams. This part of the facility provides low-energy ...
