Quantum mechanical problems can roughly be divided into two classes. The first class consists of the few ‘exactly solvable’ models, such as the harmonic oscillator, whose complete spectrum can be exactly analysed using algebraic or group-theoretical techniques. The second class then lumps together all other quantum systems, whose spectrum cannot be… (More)
