For the first time, physicists have developed a model that explains the origins of unusually stable magic nuclei based directly on the interactions between their protons and neutrons. Published in ...

Two independent research teams have achieved a longstanding goal in physics: building a working nuclear clock. The devices, developed by Beichen Huang and colleagues at Tsinghua University and by Luca ...

Most of the atomic clocks in the world — fewer than 500 in total — are housed at standards institutes and used to keep time for the planet. But the one inside UC Berkeley’s Kolkowitz Lab has a ...

Pt. 1. From the discovery of the neutron to nuclear fission. The state of nuclear physics in 193l -- Discovery of the neutron -- Discovery of the positron and artificial radioactivity -- Radioactivity ...

Andrea Richard's research is helping answer a longstanding question in nuclear physics, providing new insight into the ...

The nucleus of an atom is now the modern version of sand flowing through an hourglass. Researchers have spent 15 years trying to increase accuracy in timekeeping. The U.S. standard currently relies on ...

Fin-de-siècle physics: a world picture in flux -- The world of physics -- Discharges in gases and what followed -- Atomic architecture -- The slow rise of quantum theory -- Physics at low temperatures ...

Researchers have designed and demonstrated an ultraviolet laser that removes a major bottleneck in the development of a nuclear clock. Whereas ordinary atomic clocks keep time using transitions of ...

Researchers use a laser to excite and precisely measure a long-sought exotic nuclear state, paving the way for precise timekeeping and ultrasensitive quantum sensing. Figure 2: The precision of ...
