Consider a particle in one dimention. there is a dirac delta potential such as V=-a delat(x). The wave functions in two sides(left and right) are Aexp(kx) and Aexp(-kx) respectively. So if the momentum operator acts on the wave functions, would give two complex numbers while the momentum operator is Hermitian. what is the justification here?(adsbygoogle = window.adsbygoogle || []).push({});
