The Jordan-Wigner transformation relates different operators acting on these particles. (15[1])Fu and Kane predicted the formation of a form of these particles in topological insulators. (15[2])Jainendra Jain used the fractional quantum Hall effect to postulate the existence of the composite form of these (15[1])particles. (15[1])The relativistic effects between these particles are considered in the Weyl equation. (-5[1])The creation (15[1])and annihilation operators acting on these particles are related by an (*) anticommutator. (10[4])A normalization (10[1])factor of one over root n-factorial (-5[1])is multiplied by the Slater (-5[1])determinant (-5[2])to (10[1])analyze the wavefunction (-5[2])of a system of these particles. (-5[2])The Pauli exclusion (10[1])principle (10[2]-5[1])states (10[1])that two (10[1]-5[1])or more (-5[1])of (-5[1])these (-5[1])particles (10[2])can not occupy the same state when identical. (10[1])For 10 points, name these spin-half particles. (10[2])■END■ (10[9]0[1])
