WebRenormalization group flow of entanglement entropy on spheres Webscalar field equation is solved exactly there and consider the problem of the vacuum choice, especially particle creation caused by the difference from the standard Bunch-Davies vacuum is discussed. Furthermore, the vacuum expectation value of the energy density of the quan-tum field is calculated with the adiabatic regularization procedure.
