This course is part of a chain of quantum mechanics courses, consisting of Introduction to Quantum Mechanics and Quantum Mechanics 1a+b, 2 and 3.

In Quantum Mechanics 2 the emphasis is on the abstract formulation of quantum mechanics. In this context unitary transformations play a special role as tools for describing changes in representation, time evolution of quantum systems, as well as symmetries and conservation laws. In addition, the concept of identical particles will be introduced together with the special version of quantum mechanics that is required for their description. Finally, a detailed discussion is given of how quantum systems respond to time-dependent external influences, like electromagnetic fields and scattering interactions. To this end a few popular approximation techniques will be introduced, i.e. the WKB approximation, (a)diabatic approximation methods and time-dependent perturbation theory.
