“…The well-known Lifshitz formula turns out to be ambiguous in this respect. Depending upon how the limit of infinite dielectric constant is taken, violation of the Nernst theorem in thermodynamics has been claimed, i.e., negative entropy connected to the TE field is obtained at T = 0 [5,[30][31][32][33][34].…”

From energy considerations there is reason to expect that the work done by Casimir forces during a slow displacement of the parallel plates reflects the free energy of the surface tension of the adjacent surfaces. We show this explicitly, for a one-component ionic fluid or plasma with q c as ionic charge, where the particles are neutralized by a uniform continuous oppositely charged background. For two equal half-planes, the surface-associated free energy for one half-plane turns out to be just one half of the total Casimir energy for the conventional Casimir setup. We also comment, from a wider perspective, on the intriguing possibility that knowledge about the magnitude of the surface tension coefficient obtained from statistical mechanics or experiments may give insight into the value of the conventional cutoff time-splitting parameter τ = t − t occurring in quantum field theory. A simple analysis suggests that the minimal distance τ c is of the order of atomic dimensions, which is a physically natural result.

“…In these experiments, which are not independent measurements of the Casimir force, an agreement of the data with the Drude model approach has been claimed (see Refs. [52][53][54][55][56] for a critical discussion).…”

We obtain constraints on parameters of the Yukawa-type corrections to Newton's gravitational law from measurements of the gradient of the Casimir force between surfaces coated with ferromagnetic metal Ni and from measurements of the Casimir force between Au-coated sinusoidally corrugated surfaces at various angles between corrugations. It is shown that constraints following from the experiment with magnetic surfaces are slightly weaker than currently available strongest constraints, but benefit from increased reliability and independence of systematic effects. The constraints derived from the experiment with corrugated surfaces within the interaction region from 11.6 to 29.2 nm are stronger up to a factor of 4 than the strongest constraints derived from other experiments. The possibility of further strengthening of constraints on non-Newtonian gravity by using the configurations with corrugated boundaries is proposed.

“…The results have been interpreted by the authors as being in accordance with the Drude prescription. This experiment has been criticized [36], because the thermal Casimir force was obtained only after subtracting from the total measured force the much larger electrostatic force. The subtraction was perfomed by making a fit of the total observed force, based on a two-parameter model of the electrostatic force, and not by a direct and independent measurement, as it would have been desirable.…”

Isoelectronic differential force measurements provide a unique opportunity to probe controversial features of the thermal Casimir effect, that are still much debated in the current literature. Isolectronic setups offer two major advantages over conventional Casimir setups. On one hand they are immune from electrostatic forces caused by potential patches on the plates surfaces, that plague present Casimir experiments especially for separations in the micron range. On the other hand they can strongly enhance the discrepancy between alternative theoretical models that have been proposed to estimate the thermal Casimir force for metallic and magnetic surfaces. Thanks to these two features, isoelectronic differential experiments should allow to establish conclusively which among these models correctly describes the thermal Casimir force.
