Non-perturbative states in the 3D φ4 theory
We show that the spectrum of the three-dimensional φ4 theory in the broken symmetry phase contains non-perturbative states. We determine the spectrum using a new variational technique based on the introduction of operators corresponding to different length scales. The presence of non-perturbative st...
