fermion Definition

fer·mion (fermē än′, fʉr-)

noun

Particle Physics any of a class of subatomic particles that obey the Pauli exclusion principle and have fractional spin, including the leptons, quarks, and baryons

Etymology: after Enrico Fermi + -on

fermion Usage Examples

Converse of object

  • interact: Microscopically, however, quantal effects of the large, yet finite, ensemble of strongly interacting fermions need to be considered.
  • call: Furthermore, the resultant particles, called composite fermions, interact with each other very little.

Adjective modifier

  • staggered: This is suitable when the bounds of the approximation are known not to change, as staggered fermions.
  • heavy: The archetypal strongly correlated system is that of heavy fermions.
  • fundamental: Quark ( q ) A fundamental fermion that has strong interactions.
  • composite: A composite fermion consists of an electron ( or hole ) bound to an even number of magnetic flux quanta.
  • massless: Restrictions: The theoretical formulation is specifically worked out for massless fermions, although this is not a limitation of principle.
  • dynamical: The R2 algorithm is specifically for simulating 2+1 flavors of dynamical staggered fermions of different masses.

Modifies a noun

  • matrix: The general Wilson type of fermion matrix is where the Wilson hopping matrix D is w Note that D connects sites of opposite parity.
  • mass: A precision of 50 to 100 digits should suffice, depending on the fermion mass.
  • field: The fermion field storage order is the canonical one.
  • action: Whether the lattice fields need to be converted to to a new storage order appropriate for the type of fermion action.
  • type: The fermion field storage order is not the canonical one but it is particular to the fermion type.
  • system: Nature of problem: The output of this program describes the thermalisation by internal collisions in a nonrelativistic infinite fermion system.

Noun used with modifier

  • domain: These can be safely ignored if domain wall fermions are not being used.
  • wall: These can be safely ignored if domain wall fermions are not being used.
