    "abstract": "We calculate the energy-momentum tensor due to electromagnetic vacuum\nfluctuations between two parallel hyperplanes in more than four dimensions,\nconsidering both metallic and MIT boundary conditions. Using the axial gauge,\nthe problem can be mapped upon the corresponding problem with a massless,\nscalar field satisfying respectively Dirichlet or Neumann boundary conditions.\nThe pressure between the plates is constant while the energy density is found\nto diverge at the boundaries when there are extra dimensions. This can be\nrelated to the fact that Maxwell theory is then no longer conformally\ninvariant. A similar behavior is known for the scalar field where a constant\nenergy density consistent with the pressure can be obtained by improving the\nenergy-momentum tensor with the Huggins term. This is not possible for the\nMaxwell field. However, the change in the energy-momentum tensor with distance\nbetween boundaries is finite in all cases.",
