Observation of the topological soliton state in the Su–Schrieffer–Heeger model
Abstract
The Su-Schrieffer-Heeger model describes a system that supports topological excitations. Here the authors simulate this model using87Rb atoms in a momentum-space lattice, observing the localized topological soliton state via quench dynamics, phase-sensitive injection and adiabatic preparation.
