Precision experiment first to isolate, measure weak force between protons, neutrons

A team of scientists has for the first time measured the elusive weak interaction between protons and neutrons in the nucleus of an atom. They had chosen the simplest nucleus consisting of one neutron and one proton for the study. Through a unique neutron experiment, experimental physicists resolved the weak force between the particles at the atom's core, predicted in the Standard Model that describes the elementary particles and their interactions.

Researchers make liquid crystals do the twist

Researchers have for the first time measured an effect that was predicted more than 40 years ago, called the Casimir torque.

New study on low noise and high-performance transistors could bring innovations in electronics, sensing

A research study on low noise and high-performance transistors led by Suprem Das, assistant professor of industrial and manufacturing systems engineering, in collaboration with researchers at Purdue University, was recently published by Physical Review Applied.

The coming of age of plasma physics

The story of the generation of physicists involved in the development of a sustainable energy source, controlled fusion, using a method called magnetic confinement.

Radium revealed: 120 years since the Curies found the most radioactive substance on the planet

Scientific discovery can be achingly slow, but it was moving swiftly in the 1890s. X-rays had been discovered in Germany just a few days before Christmas in 1895. Several months later, while researching these new X-rays, the French physicist Henri Becquerel accidentally discovered another new mysterious type of ray when he detected radiation emitting from uranium.

Scientists find a way to connect quantum and classical physics

Physicists from Skoltech have invented a new method for calculating the dynamics of large quantum systems. Underpinned by a combination of quantum and classical modeling, the method has been successfully applied to nuclear magnetic resonance in solids. The results of the study were published in Physical Review B.

Physics instructor writes book on shock waves

A sonic boom and a thunderclap may seem like different phenomena, but their behavior is the same, according to SDState Physics Instructor W. Robert Matson. This is one of the ways he explains shock waves in "Sonic Thunder," his latest book.

Proton scattering reveals the secrets of strongly-correlated proton-neutron pairs in atomic nuclei

The nuclear force that holds protons and neutrons together in the center of atoms has a non-central component—the tensor force, which depends on the spin and relative position of the interacting particles.

GlueX completes first phase

An experiment that aims to gain new insight into the force that binds all matter together has recently completed its first phase of data collection at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility.
