Composite fermions are exotic quasi-particles found in interacting 2-D fermion systems at relatively large perpendicular magnetic fields. These quasi-particles, which are composed of an electron and ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. There are only two types of fundamental particle known in the entire ...

Quasiparticles that behave like massless fermions, known as Weyl fermions, have been in recent years at the center of a string of exciting findings in condensed matter physics. Physicists now report ...

A collaboration between Stuart Parkin's group at the Max Planck Institute of Microstructure Physics in Halle (Saale) and Claudia Felser's group at the Max Planck Institute for Chemical Physics of ...

Inside materials, the interactions between groups of electrons and atoms in the crystal lattice can give rise to a variety of interesting phenomena. Their collective behavior, especially at low ...

Today, quantum optical experiments provide methods to prove the rules that have been thought of and pressed into elegant mathematical equations in those days, say scientists. The microcosm is governed ...

Definition: Majorana fermions are enigmatic particles that act as their own antiparticles, distinguished by their neutral charge and the ability to annihilate themselves. Their theoretical existence ...

Physicists in the Netherlands say that they have found the first evidence for the existence of “Majorana fermions” – particles that are their own antiparticles. The researchers claim to have spotted ...
