The QCD vacuum (i.e., the ground state of vacuum in the quantum chromodynamics regime) is theoretically characterized by the presence of non-zero expectation values of condensates, such as gluons and quark–antiquark pairs. ...
Thirty-seven years ago, on April 26 1986, the reactor of the Chernobyl nuclear power plant suffered a catastrophic meltdown. In the weeks that followed, the deadly event drove hundreds of thousands of people to relocate from ...
Japanese authorities are preparing to release treated radioactive wastewater into the Pacific Ocean, nearly 12 years after the Fukushima nuclear disaster. This will relieve pressure on more than 1,000 storage tanks, creating ...
While not primarily useful for telling the time, nuclear clocks could allow scientists to test humankind's fundamental understanding of how reality works.
Atomic nuclei take a range of shapes, from spherical (like a basketball) to deformed (like an American football). Spherical nuclei are often described by the motion of a small fraction of the protons and neutrons, while deformed ...
In principle, quantum-based devices such as computers and sensors could vastly outperform conventional digital technologies for carrying out many complex tasks. But developing such devices in practice has been a challenging ...
A team led by Professor Andrea Morello at UNSW Sydney has just demonstrated the operation of a new type of quantum bit, called "flip-flop" qubit, which combines the exquisite quantum properties of single atoms with easy controllability ...
A team of theorists has extended their previous critical analysis of the Lead Radius Experiment (PREX). The experiment involved deducing the neutron size of a lead atom's nucleus by measuring a tiny left-right asymmetry in ...
At the end of 2022, researchers at Lawrence Livermore National Laboratory announced they had observed a net energy gain through nuclear fusion for the very first time. This monumental milestone toward fusion energy represents ...
There is no good place to be when a nuclear bomb goes off. Anything too close is instantly vaporized, and radiation can pose a serious health threat even at a distance. In between, there is another danger: the blast wave ...
