Phonons are sound particles or quantized vibrations of atoms in solid materials. The Debye model, a theory introduced by ...

A new theory-based approach provides access to the minute transverse motion of quarks within protons. Nuclear physicists have developed a new theoretical framework that allows them to calculate a ...

String theory unifies all the forces of nature. Forces that seem very different, such as gravity and electricity, are deeply ...

Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter candidates. Unlike axions or WIMPs, these particles carry electric charge but ...

Overcoming discrimination in a mostly male preserve, she did groundbreaking work that showed experimentalist physicists where and how to look for new particles. By Katrina Miller Mary K. Gaillard was ...

Offering scholars and enthusiasts unprecedented access to the works of one of the most influential theoretical physicists of the 20th and early 21st centuries, the UC Santa Barbara Library has ...

Scientists are on the trail of a mysterious five-particle structure that could challenge one of the biggest theories in physics: string theory. This rare particle—never seen before and predicted not ...

When trying to answer questions as deep as “what makes up the universe,” advance planning is key. On June 11, the National Academies of Science, Engineering and Medicine announced the result of a ...
