The expectation value of an operator in quantum mechanics is the expected value of the operator, and can be considered to be a type of average value of the operator. It is not necessarily the most probable value. For example, in the case of a particle in a 1-D box. The ...
The application h(p) of h∈E(X) to a function p∈[0,1]X may then be understood as integration ∫pdh, giving the expected value of the stochastic variable/predicate p for the measure h. (2) The description E(X)=EMod([0,1]X,[0,1]) of the expectation monad in (11) bears a...

quantum mechanics. In section IV we explicitly calculate the momentum expectation values in various potentials and show that in bound states we always get the expectation value of the linear momentum to be zero. Section V gives a brief discussion on the Ehrenfest theorem when we are using it to...

in which E denotes the expectation value. Notice that the matrix A in eqn (10) has equal elements along each of the diagonals, i.e., it is Toeplitz. The vector b has elements which are equal to the values of the cross-correlation function between the reference signal and the desired si...
We studied the challenges students face with time dependence in quantum mechanics, specifically in the context of Larmor precession of spin. This research informed the creation and evaluation of a learning tutorial aimed at helping students grasp these concepts using a two-state system. The tutorial...
