  "abstract": "Quantum fluctuations can unbind a composite soliton while the correction to its mass stays small. We show this beyond perturbation theory for the multi-kinks of the non-degenerate double sine-Gordon model. At one loop the vacuum at the centre of the multi-kink becomes the true vacuum at a coupling of order the classical lifting of the vacua. Tensor-network calculations of the lattice theory show that this inversion survives beyond one loop and has a continuum limit, and that the Gaussian effective potential captures it. On finite chains the multi-kink unbinds when the tension of the string of central vacuum between its two halves falls through zero",
