A quantum energy inequality is derived for the massive Ising model, giving a state-independent lower bound on suitable averages of the energy density, the first quantum energy inequality to be established for an interacting quantum field theory with nontrivial $S$-matrix. It is shown that the Ising model has one-particle states with locally negative energy densities and that the energy density operator is not additive with respect to the combination of one-particle states into multiparticle… Expand
