... and it defines the number of different states in this region. It is impossible to have more different states because there is no way to distuingush states that are too close both in x and in px by any measurement. Similarly, quantum cells can be introduced in many-particle problems and in problems w ...

Operator methods in quantum mechanics
... This is clearly a discrete transformation. Application of parity twice returns the initial state implying that P̂ 2 = 1. Therefore, the eigenvalues of the parity operation (if such exist) are ±1. A wavefunction will have a defined parity if and only if it is an even or odd function. For example, for ...
