There are only three kinds of matrix elements that play a significant role in the theory.

For the electron–phonon matrix element 15 plane waves are included.

There are numerous ways to get parameters for these matrix elements.

Assume that a single memory location can hold one matrix element.

Each matrix element is assumed to be associated with a coordinate point in the plane.

The numerical solutions are then used to evaluate a number of matrix elements to order α2.

A new value, 1.2 cm3, has been obtained for the matrix element of the polarizability.

Matrix elements are important in atomic, nuclear and particle physics.

This model leads to an unique formula for matrix elements of these operators.

Matrix elements are not restricted to constant numbers, they can be mathematical variables.

Therefore there appear interference terms in the absolute square of the matrix element.

Matrix elements with value 0 indicate the absence of interactions between two genes.

The phase of this matrix element, however, contains separate information about the transition process.

We present here the first calculation of this interaction due to the spin–orbit contribution to the electron–phonon matrix element.

The Hamiltonian matrix elements for the system are given.

From these, matrix elements of the group generators are calculated using the procedures discussed here.

The nonzero matrix elements can only come from the spin-0 subspace.

Consider next the matrix element appearing in the integral.

"Matrix element calculation and a selection rule in the unitary group approach", Can.

We may also use the matrix elements of in the Fock basis .

Now we can determine the matrix elements of the Hamiltonian:

The eigenvectors are used to calculate the electric-dipole matrix elements.

The derivation of the reduced matrix elements is provided.

The interaction is described by its harmonic-oscillator matrix elements.

The actual form of the matrix elements of B can be fairly complicated.
