fermions

(fer -mee-on) A class of elementary particles with half integer units of spin; examples are electrons, protons, and neutrinos. No two fermions can exist possessing an identical set of quantum numbers (numbers assigned to the various quantities that describe a particle). Compare bosons.

In fact, when one examines the structure of the allowed terms in the effective Lagrangian, a general pattern emerges: the lowest order coupling of the Higgs to fermions will generally contain either one or two factors of [SIGMA].
They just behave as if they have, and, by assuming that the Majorana fermions are real - rather than quasiparticles - scientists can explain the behavior of quantum spin liquids.
Three of these quasiparticles, the Dirac, Majorana, and Weyl fermions, were discovered in such materials, despite the fact that the latter two had long been elusive in experiments, opening the path to simulate certain predictions of quantum field theory in relatively inexpensive and small-scale experiments carried out in these "condensed matter" crystals.
Previously, scientists have published ideas about how to engineer the elusive Majorana fermions, but no team had actually constructed such a device.
In order to compare masses of fermions, it is necessary to consider them as objects possessing inner structure.
Amongst the approaches that could pave the way to energy efficient electronics of the future, Weyl fermions could play an intriguing role.
Rockenbauer's brilliant paper on the extended dirac equation for elementary fermions is a great contribution in the sphere of physics.
Pisano & Pleitez (1992) shown that, for b = 3/2, the following fermion structure is free of all the gauge anomalies: [[psi].sup.T.sub.lL] = [([v.sup.0.sub.l], [l.sup.-], [l.sup.+]).sub.L] ~ (1, 3, 0), [Q.sup.T.sub.lL] = [([d.sub.i], [u.sub.i], [X.sub.i]).sub.L]~(3, 3*,-1/3), [Q.sup.T.sub.L] = (u3, d3, Y-3, 3, 2/3), where l = e, [mu], [tau] is a family lepton index, i = 1, 2 for the first two quark families, and the numbers after the similarity sign means 3-3-1 representations.
Time crystals and quasiparticles called Majorana fermions have made headlines in recent years thanks to the fact they're both so incredibly weird.
Elementary quantum particles are classified into bosons and fermions based on integral and half-integral multiples of [??] respectively, where [??] is Planck's reduced constant.
Instead of applying the mean field decoupling, we shall transform the quartic terms to a quadratic form by introducing a four-component boson field which mediates the interaction of fermions in the same manner as in quantum electrodynamics, where the photons mediate the interaction of electric charges.
Recently, the GUP modified Hamilton-Jacobi equations for fermions in curved spacetime have been introduced and the corrected Hawking temperatures have been derived [29-34].
