Two- and three-body interactions in $$\varphi ^4$$ φ4 theory from lattice simulations
Abstract We calculate the one-, two- and three-particle energy levels for different lattice volumes in the complex $$\varphi ^4$$ φ4 theory on the lattice. We argue that the exponentially suppressed finite-volume corrections for the two- and three-particle energy shifts can be reduced significantly...
