The reason is that the system is in a state of superposition just before the measurement is performed, whereas after the measurement it takes, qua projection, the
eigenstate of that operator that has been assigned to the observable to be measured.
by displaying the contribution of the s and p orbitals to the charge distribution of an
eigenstate of the triple pyramid quantum dot.
Such a state is an unfathomably complicated mix of
eigenstates of the true system yet it makes some sense to think of the excitations of the bodies in terms of collective phonon modes as
eigenstates in such clumps of matter.
The primes on the fields indicate that they are the weak
eigenstates.
We report the accurate calculation of ro-vibrational
eigenstates of the ground electronic state of hypochlorous acid, HOCI.
The design of the lattice requires only one conversion of the electric charge, so involving only two charge
eigenstates (the SU(2) doublet).
In the nuclear shell model, successive levels alternate in parity, and so parity
eigenstates are linear combinations of either even (|nh[omega]>, n even) or odd (|nh[omega]>, n odd) shell states.
Experiments have determined that the left-handed EW isospin flavor states are linear superpositions of mass
eigenstates.
Exploiting this equivalence there is in principle no difference between manipulations in the spin space of neutrons with the orthogonal basis {|[up arrow]>, |[down arrow]>} as
eigenstates of [[sigma].
The
eigenstates of the the Hamiltonian 1 associated with the number v of quanta and definite seniority [lambda], angular momentum L and projection M can be denoted by the Ket
Finally, motional
eigenstates are not required as long as the ions are tightly contained and within the Lamb-Dicke limit.
However, experiments have determined that these left-handed flavor states are linear superpositions of mass
eigenstates.
