SOME POINTS ON CASIMIR FORCES
Casimir forces of massive ferrnionic Dirac fields are calculated for parallel plates geometry in spatial space with dimension d and imposing bag model boundary conditions. It is shown that in the range of ma>>l where m is mass of fields quanta and a is the separation distance of the plates, it is equal to massive bosonic fields Casimir force for each degree of freedom. We argue this equalit...
متن کاملSome Chemical Aspects of the Potassium Effect
The ability of Nitella to distinguish electrically between Na(+) and K(+) (potassium effect) appears to depend on several organic substances (or groups of substances). Of these R(MK) and R(SK) determine the mobility and partition coefficient (S) respectively of K(+) while R(MNa) and R(SNa) do the same for Na(+). These substances can vary independently and this variation is susceptible to experi...
متن کاملSome Mathematical Aspects of the Lifshitz Formula for the Thermal Casimir Force
The applicability of the Lifshitz formula is discussed to the case of two thick parallel plates made of real metal. The usual description of the zero-point vacuum oscillations on the background of the frequency-dependent dielectric permittivity is shown to be in contradiction with thermodynamics. Instead, the Lifshitz formula for the Casimir free energy should be reformulated in terms of the re...
