We have tried to point out most of the elementary quantum mechanical results, related to the momentum operator, which has coordinate dependence. We explicitly calculate the momentum expectation values in various bound states and show that the expectation value really turns out to be zero, a ...
of the fact that the expectation value of the momentum operator in various bound states are zero, a result which most of the textbooks only quote but never show. In the simpler cases the result can be shown by one or two lines of calculation, but in nontrivial potentials as the Morse po...
particle in a 1-D box. The expected value of the particle's momentum is zero because it has equal probability of moving either to the left or to the right, however zero is not the most probable speed, as it will always have some momentum. Mathematically the expectation value ...
February 1, 2020 Published: February 17, 2020 Expectation value of TT operator in curved spacetimes Yunfeng Jiang Theoretical Physics Department, CERN, Geneva, Switzerland E-mail: jinagyf2008@gmail.com Abstract: We study the expectation value of the TT operator in maximally symmetric spacetimes. ...
In this paper we prove that, even though the interference pattern shifts, none of the moments of the electron's positionr, nor of its kinetic momentumπ, are affected. On the other hand, we prove that the expectation value of the operator sina·π(withaa certain fixed vector), which was...
The weight operator has been constructed in such a way that certain number of expectation values of position operator's first positive integer powers with and without the chosen weight operator match. Therein this match has not been considered for the momentum operator's corresponding power ...
This average result is called the expectation value of the operator. The spread of the results about the expectation value can be obtained from the mean square variation (the variance): (ΔO)2=∫ψ∗(O^−⟨O^⟩)2ψd3r.
