The Jordan-Wigner transformation relates different operators acting on these particles. Fu and Kane predicted the formation of a form of these particles in topological insulators. Jainendra Jain used the fractional quantum Hall effect to postulate the existence of the composite form of these particles. The relativistic effects between these particles are considered in the Weyl equation. The creation and annihilation operators acting on these particles are related by an (*) anticommutator. A normalization factor of one over root n-factorial is multiplied by the Slater (-5[1])determinant (-5[2])to analyze the wavefunction of a system of these particles. The Pauli exclusion principle states that two or more of these particles (10[1])can not occupy the same state when identical. For 10 points, name these spin-half particles. ■END■ (10[3])
