Comment on the sign of the Casimir force
I show that reflection positivity implies that the force between any mirror pair of charge-conjugate probes of the quantum vacuum is attractive. This generalizes a recent theorem of Kenneth and Klich [9] to interacting quantum fields, to arbitrary semiclassical bodies, and to quantized probes with nonoverlapping wavefunctions. I also prove that the torques on charge-conjugate probes tend always...
متن کاملCasimir Force in Compact Noncommutative Extra Dimensions and Radius Stabilization
We compute the one loop Casimir energy of an interacting scalar field in a compact noncommutative space of R × T 2 θ , where we have ordinary flat 1 + d dimensional Minkowski space and two dimensional noncommuative torus. We find that next order correction due to the noncommutativity still contributes an attractive force and thus will have a quantum instability. However, the case of vector fiel...
متن کاملCasimir force on a piston
We consider a massless scalar field obeying Dirichlet boundary conditions on the walls of a two-dimensional L×b rectangular box, divided by a movable partition (piston) into two boxes of dimensions a × b and (L − a) × b. We compute the Casimir force on the piston in the limit L → ∞. Regardless the value of a/b, the piston is attracted to the nearest end of the box. Asymptotic expressions for th...

متن کاملComment on “Surface-impedance approach solves problems with the thermal Casimir force between real metals”
In a recent paper Geyer, Klimchitskaya, and Mostepanenko [Phys. Rev. A 67, 062102 (2003)] proposed the final solution of the problem of temperature correction to the Casimir force between real metals. The basic idea was that one cannot use the dielectric permittivity in the frequency region where a real current may arise leading to Joule heating of the metal. Instead, the surface impedance appr...
