On the non-relativistic Casimir effect

Abstract: , we use the non-relativistic one, omega(p) = p²/2m. It turns out that the Casimir energy is zero. We include the relativistic corrections perturbatively and show that at all orders the Casimir energy remains zero, since each term in the power series in 1/c² is proportional to the Riemann zeta function of a negative even integer. This puzzling result shows that, at least for the free massive scalar field, the Casimir effect is non-perturbative in the relativistic sense.]]>

“…Since the mode sum (4) only contains odd derivatives of F , the generalized Casimir effect is absent for any function that for small wave vectors vanishes as an even power of the wavevector. Specifically, this rules out the possibility of the Casimir effect with "non-relativistic" dispersion law F (q → 0) ∝ q 2 ; the same conclusion holds in the parallel plane geometry in three spatial dimensions [19,26]. However below we will demonstrate a possibility of a nonrelativistic Casimir effect in spherical shell geometry.…”

“…The noteworthy features of this expression, compared to its scalar counterpart (14), are lack of the F ′′ (0) term; the possibility of taking the limit of infinite cutoff scale; and the lack of dependence on the form of the cutoff function itself. The cutoff function did play a role, however: from the large ν and y dependences of (26) we can see that in the absence of the cutoff function, the integral (24) converges and the sum (23) diverges. The effect of the cutoff function is to prevent the change in variables that would allow doing these calculations sequentially.…”

“…These two later aspects can be improved by considering the size-effect of the vacuum fluctuation at finite temperature. Regarding the vacuum fluctuation, some analyses of the so called Casimir effect are only partially explored [5] and by considering the non-relativistic limit of the relativistic massive Klein-Gordon field, the results are inconclusive [6]. Our main goal is to address these three parts, by considering the symplectic quantum field theory formulated in a torus at finite temperature.…”
