Suppose we have a particle enclosed in a well, where one wall is movable, as shown in the figure below.
Solve Schrödinger equation for a particle in a box provides the following result:
Moving the wall of the box can be increased or decreased the energy of the particle therefore it is necessary to perform work or a force throughout the space.
If energy is derived with respect to gives the expression of power that takes place on the wall:
Solving the Schrödinger equation for a particle in a box provides the following result:
As shown is a force that varies with the inverse cube of the distance.
Now suppose you have two electrons, each of which are confined in a box. One box is fixed to the origin of coordinates while the other can move freely along the axis X. The box dimensions are fixed and do not change over time. Now between the boxes is confined photon having a wavelength that is 1 / 2 the distance between the two boxes (1 st harmonic):
will be calculated the expression of force:
is appreciated that the strength decreases with the square of the distance, the use of conventional forces, however, proportionality is different Culomb law as can be seen: There shall to evaluate the expression of force:
words, the force would in any case the order of 1727 times greater than that due to the electrostatic repulsion.
