Pp. 1-191367-2630 (Online)https://hdl.handle.net/10016/14039The escape of solitons over a potential barrier is analysed within the framework of a nonlinear Klein–Gordon equation. It is shown that the creation of a kink–antikink pair near the barrier through an internal mode instability can be followed by escape of the kink in a process analogous to Hawking radiation. These results have important implications in a wider context, including stochastic resonance and ratchet systems, which are also discussed.application/pdfengAtribución-NoComercial-SinDerivadas 3.0 EspañaHawking-like emission in kink-soliton escape from a potential wellresearch articleMatemáticas10.1088/1367-2630/10/11/113015open access119New Journal of Physics: the open access journal for physicsvol. 10
