Generalization of Exact Operators of the Foldy-Wouthuysen Transformation to Arbitrary-Spin Particles in Nonstationary Fields / A.J.Silenko. – Text: electronic // Physical Review A. – 2025. – Vol. 111, No. 5. – P. L050203. – URL: https://doi.org/10.1103/PhysRevA.111.L050203.

Time-dependent terms in Hamiltonians and equations of motion are rather important for a quantum-mechanical description of particles with arbitrary spins in nonstationary fields. We use the Foldy-Wouthuysen representation which allows one to obtain the Schrödinger picture of relativistic quantum mechanics. We determine exact nonexponential and exponential operators of the Foldy-Wouthuysen transformation for arbitrary-spin particles in the nonstationary case. Some fundamental properties of these operators and the Foldy-Wouthuysen Hamiltonian are also identified.
