It was shown recently that in four dimensions scalar sources with fixedproper acceleration minimally coupled to a massless Klein-Gordon field lead tothe same responses when they are (i) uniformly accelerated in Minkowskispacetime (in the inertial vacuum) and (ii) static in the Schwarzschildspacetime (in the Unruh vacuum). Here we show that this equivalence is brokenif the spacetime dimension is more than four.Comment: 4 pages, 1 figur

Is the equivalence for the response of static scalar sources in the Schwarzschild and Rindler spacetimes valid only in four dimensions?
