Two-loop scalar kinks

At one loop, quantum kinks are described by a sum of harmonic oscillator Hamiltonians, and the ground state is just product states. Two-loop kink masses only known in integrable supersymmetric cases two-loop states have never been found. We find mass explicitly construct scalar field theory with an arbitrary nonderivative potential. use coherent operator which maps vacuum sector to sector, allowing all be treated single Hamiltonian needs renormalized once, eliminating need for regulator matching conditions. Our calculation greatly simplified recently introduced alternative collective coordinates, momentum fixed perturbatively.
