Probability flux and momentum
Webb3 sep. 2024 · It seems to be like the answer should be yes- When you measure the momentum, it can come out as per the momentum probability distribution, but once you have measured it, the system comes into a pure state of momentum. So, in that case all the positions of the particle are equally likely.

Webb5 feb. 2024 · This can be interpreted as the electron having a momentum magnitude of h/2L but having an unknown direction for this momentum. Thus the momentum is: (6.4.19) p = 0 ± h 2 L Finally, we can verify that the uncertainty in position and momentum are consistent with the uncertainty principle: WebbTo start we set up a momentum balance in the z direction over a system Ax thick, bounded in the z direction by the planes z = 0 and z = L, and extending a distance W in the y …
WebbMomentum and the velocity both are in the same direction. Scientists do the calculation of the momentum by doing the multiplication of the mass of the object and the velocity of … In quantum mechanics, the probability current (sometimes called probability flux) is a mathematical quantity describing the flow of probability. Specifically, if one thinks of probability as a heterogeneous fluid, then the probability current is the rate of flow of this fluid. It is a real vector that changes with space and time. … Visa mer Continuity equation for quantum mechanics The definition of probability current and Schrödinger's equation can be used to derive the continuity equation, which has exactly the same … Visa mer • Resnick, R.; Eisberg, R.
