Probability Current and Current Operators in Quantum Mechanics 1
... In the real space representation of QM, the momentum operator is p̂ = −ih̄∇, potential depends only on the space coordinates and time. The main topic of these notes is to find and describe the operations and operators that would be used to calculate the electric currents associated with the motion o ...

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 ...
