Infinite-dimensional symmetry opens up possibility of a new physics—and new particles

The symmetries that govern the world of elementary particles at the most elementary level could be radically different from what has so far been thought. This surprising conclusion emerges from new work published by theoreticians ...

Flexy, flat and functional magnets

In the nanoworld, magnetism has proven to be truly surprising. Magnetic 2-D materials just a few atoms thick could provide a substrate for ever-smaller post-silicon electronics. An international research team led by Park ...

Breaking supersymmetry

The remarkable discoveries and theories of physicists since the 1930s have shown that all matter in the universe is made from a small number of basic building blocks called fundamental particles. However, this isn't the complete ...

Graphene enables clock rates in the terahertz range

Graphene—an ultrathin material consisting of a single layer of interlinked carbon atoms—is considered a promising candidate for the nanoelectronics of the future. In theory, it should allow clock rates up to a thousand times ...

Neutron stars may hold an answer to neutron puzzle on Earth

According to University of Illinois physicist Douglas H. Beck, "Neutrons play some unusual roles in our world. Free neutrons decay in about 900 s but, bound in nuclei, they are stable and make up somewhat more than half the ...
