This is of course identical to the equation we found for ˆ→L, but there we derived if from the quantum angular momentum operator including the momentum components written as differentials. But up to this point ψ(→r) has just been a complex valued function of position.

WebJun 3, 1998 · Eigenvalue-Eigenstate Link: A system S determinately has physical property P if and only if P operating on S (the vector representing S's state) yields S. We say then that S is in an eigenstate of P with eigenvalue 1. ... But instead of position being made determinate, as it is in Bohm's theory, and then hoping that the determinate positions of ... WebAnswer (1 of 6): If you assume a free particle with \delta P=0, assume also that you have set your uniform potential to zero, this means that you have a situation with, say, a cosine function from -\infty to \infty where your particle can be anywhere along this cosine wave. So, as Sergey Lourie c...

When the position operator is considered with a wide enough domain (e.g. the space of tempered distributions), its eigenvalues are the possible position vectors of the particle.
