A low-temperature material made from the elements praseodymium, osmium, and antimony should be able to host subatomic particles known as Majorana fermions, MIT researchers have shown in a theoretical analysis.

(Phys.org)—Last year, two teams working at the LHC reported that they had found proton-to-proton collisions that had led to the creation of more photon pairs (with energies of approximately 750 GeV) than was expected, leading ...
In normal conductive materials such as silver and copper, electric current flows with varying degrees of resistance, in the form of individual electrons that ping-pong off defects, dissipating energy as they go. Superconductors, ...

The most common particles are electrons and photons, which are understood to be examples from the great families of fermions and bosons, to which all other particles in nature belong. But there is another possible category ...

A 2017 report of the discovery of a particular kind of Majorana fermion—the chiral Majorana fermion, referred to as the "angel particle"—is likely a false alarm, according to new research. Majorana fermions are enigmatic ...
