Abstract: (Springer)
For QFT on a lattice of dimension d3d\geqslant 3, the vacuum energy (both bosonic and fermionic) is zero if the Hamiltonian is a function of the square of the momentum, and the calculation of the vacuum energy is performed in the ring of residue classes modulo NN. This fact is related to a problem from number theory about the number of ways to represent a number as a sum of dd squares in the ring of residue classes modulo NN.
