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. (-5[1])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 (15[1])Weyl equation. The creation and annihilation operators acting on these particles are related by an (*) anticommutator. (-5[1])A normalization (10[1])factor of one over root n-factorial is multiplied by the Slater determinant to analyze the wavefunction of a system of these particles. The Pauli exclusion principle states that two or more of these particles can not occupy the same state when identical. For 10 points, name these spin-half particles. ■END■ (10[2])
