fer·mi·on

 (fûr′mē-ŏn′, fĕr′-)
n.
Any of a class of particles having a spin that is half an odd integer and obeying the exclusion principle, by which no more than one identical particle may occupy the same quantum state. The fermions include the baryons, quarks, and leptons.

[After Enrico Fermi.]

Taking the generic structures we have identified, we then perform a [chi square] fit to the data, allowing for the possibility that different fermions couple in different ways.
Editors Rho and Zahed present readers with the second edition of their collection of reviews by the worldAEs leading physicists or the Skyrme hypothesis of 1960, that fermions can arise from bosons via topographical solitons.
They were able to spot this evidence in the material by observing what is known as "electron fractionalisation" - wherein electrons appear to break apart - and the resulting quasiparticles called "Majorana fermions," which are created when electrons in a quantum spin state split apart. 
These quasiparticles, dubbed Bloch electrons, are also fermions.
But Majorana fermions, first theorized over 70 years ago, are a class of particles that are their own antiparticle.
The possibility of reciprocal transformations of fermions and bosons forms does not mean that a micro-particle can stay simultaneously in two states, but it shows that a mass (an energy) can have two states and pass from one form to another.
From 2012 to 2016, the DFG funded Janssen's project 'Quantum Phase Transitions and Critical Phenomena in Graphene' - a class of materials whose single-layer, honeycomb-like atomic structure can serve as a two-dimensional experimental laboratory for microparticle systems such as relativistic fermions. Janssen sums up, 'there began my intensive research on quantum-critical matter' and his special fascination for their physics: 'Quantum materials combine several exciting and highly topical areas of physics: Although we are primarily solid-state physicists, our research ranges from sophisticated mathematical Concepts of high-energy physics, aspects of quantum information theory and the synthesis of new magnetic materials in collaboration with materials scientists and chemists.
About half of the book is devoted to appendices on such matters as quantum fields of fermions, quantum electrodynamics in terms of particle operators, scattering matrix in (v/c)2, and checks of physical dimensions.
