We analyze the reflection and transmission of a soliton when it propagates through the domain wall, and we show that a dark-bright soliton can be dynamically generated by the interaction of the dark soliton with the domain wall, outside the regime of parameters where stationary solutions are known to exist. The dynamics of this dark-bright soliton is harmoniclike, with a numerical frequency that is in good agreement with the predictions of a semianalytical model.application/pdfeng(c) American Physical Society, 2021Condensació de Bose-EinsteinSolitonsTeoria quànticaBose-Einstein condensationSolitonsQuantum theoryinfo:eu-repo/semantics/article7153262021-12-17info:eu-repo/semantics/openAccess
