Rotational Invariance of Magnetic Monopoles
Rotational Invariance of Magnetic Monopoles is a scholarly work, published in 1968 in ''Physical Review''. The main subjects of the publication include quantization, free-electron laser, physics, integer data type, quantum electrodynamics, mathematical physics, gauge theory, magnetic monopole, quantum mechanics, invariance principle, rotational invariance, superconducting magnet, and theoretical physics. The Schwinger quantization relation for magnetic charges, $g=\frac{n\ensuremath{\hbar}c}{e}$ ($n$ integer), is derived by purely group-theoretic methods, from the combined requirements of rotational invariance and gauge invariance.
