Explainer: What are fundamental particles?

It is often claimed that the Ancient Greeks were the first to identify objects that have no size, yet are able to build up the world around us through their interactions. And as we are able to observe the world in tinier ...

Exotic states materialize with supercomputers

Scientists used supercomputers to find a new class of materials that possess an exotic state of matter known as the quantum spin Hall effect. The researchers published their results in the journal Science in December 2014, ...

Simplicity will out: Novel experiment-based expression explains behavior of unconventional superconductors

(Phys.org)—Superconductivity – perhaps the leading example of emergent quantum behavior in matter – was discovered in 1911 but lacked theoretical explanation for almost five decades. In 1957, John Bardeen, Leon Cooper, and ...

A Higgs-gravity connection may leave traces in white dwarfs

(Phys.org) —The discovery of the Higgs boson at the Large Hadron Collider (LHC) in 2012 marked an important step toward understanding the origin of the mass of fundamental particles. Since mass plays a major role in gravity, ...

Ultracold atoms juggle spins with exceptional symmetry

The physical behavior of materials is strongly governed by the many electrons which can interact and move inside any solid. While an individual electron is a very simple object, carrying only mass, electric charge, and an ...
