Unlock the power of group theory in quantum mechanics with this advanced text from The Bookish Owl. Tailored for postgraduate students, theoretical physicists, and researchers, this book offers a lucid guide to modern group-theoretical methods essential for quantum theory. Explore concepts from matrix representations to point, space, and continuous rotation groups, with practical applications in electronic and vibrational states. Delve into permutation groups, Lorentz groups, and the symmetry properties of the Schrodinger wave function. This comprehensive resource, rooted in a prominent Soviet university physics course, also tackles “additional” degeneracy in the Coulomb field and conditions for relativistic invariance. A must-have for deepening your understanding of quantum physics.
