Poincare Group and Operators of Position and Spin : [Abstract] / A.J.Silenko, P.Zhang, L.Zou // Физика элементарных частиц и атомного ядра. – 2023. – Т.54, №6. – P.1176. – URL: http://www1.jinr.ru/Pepan/v-54-6/19_Silenko_ann.pdf.

Fundamental properties of the position and spin operators in relativistic quantum mechanics are defined with the Poincar´e group. Quantum-mechanical counterparts of the classical position and spin variables are the corresponding operators in the Foldy–Wouthuysen representation but not in the Dirac one. The probabilistic interpretation is valid only for Foldy–Wouthuysen wave functions. The relativistic operators of the position and spin are discussed.
