RT Journal Article T1 Kinks and the Heisenberg uncertainty principle A1 Fernández-Rañada, Antonio AB The Lieb form of the Heisenberg relations is applied to the kinks of a nonlinear Dirac field. It is found that these relations are violated for large enough values of the self-coupling constant. A close relation between this violation and the norm of the kinks is established.
