Quantum Mechanics and Group Theory
摘要
With the mathematical groundwork laid, we can now delve into the connection between group theory and quantum mechanics.Group theory and quantum mechanics Since we first have to go through the two more technical Sects. 6.1 and 6.2, we want to start by pointing out the main goal of this chapter: As we will see in Sect. 6.3, the eigenspaces of HamiltoniansEigenspaces of Hamiltonians are completely determined by group theory as far as their degeneracy and their symmetry properties are concerned.
