The Casimir energy for a compact dielectric sphere is considered
in a novel way, using the quantum statistical method introduced by
Høye-Stell and others. Dilute media are assumed. It turns out that
this method is a very powerful one: we are actually able to derive
an expression for the Casimir energy that contains also the negative
part resulting from the attractive van der Waals forces between the
molecules. It is precisely this part of the Casimir energy that has
turned out to be so difficult to extract from the formalism when using
the conventional field theoretical methods for a continuous medium.
Assuming a frequency cutoff, our results are in agreement with those
recently obtained by G. Barton [J. Phys. A: Math. Gen. 32, 525
(1999)].
neat info
then to read this
chosen. The Casimir effect as such is now a well-known effect in physics [1]. It is ordinarily examined with the use of field theory in dielectric media, allowing the medium to possess a refractive index n (even dispersive effects can in principle be dealt with in this way, if n is assumed to depend on the frequency)
and
In this geometrical configuration the phenomenological electromagnetic theory, as constructed mainly by Lifshitz [2] is fully adequate, and leads to a prediction for the Casimir force between
the plates that has recently been verified experimentally to an impressive
accuracy of about one per cent
without me posting any of my ideas, can someone share what the total potential would be (chemically speaking) if the 'n' is a 'f' or state of energy causing these 'effects'?
Does this share that the potential is governed by the 'f'?
look at their own question
Faced with this field theoretical result one becomes however surprised, for the following physical reason: the Casimir energy should be the cooperative result of the van der Waals forces between the molecules in the ball. The van der Waals forces are necessarily attractive. How can these forces sum up to give a repulsive total surface force?
it seems like a 'coherance'..................... would you agree?
