Abstract: We analyse the scattering of sine-Gordon breathers on a square potentialwell. We show that the scattering process depends not only on the vibrationfrequency of the breather and its incoming speed but also on its phase as wellas the depth and width of the well. We show that the breather can pass throughthe well and exit with a speed different, sometime larger, from the initialone. It can also be trapped and very slowly decay inside the well or bounce outof the well and go back to where it came from. We also show that the breathercan split into a kink and an anti-kink pair when it hits the well.
