Experimental Realization and Phase-Space Winding of a Topological Defect State in the Quantum Rabi Model

We experimentally realize a topological defect state of the quantum Rabi model in a single trapped $^{171}\mathrm{Yb}^{+}$ ion. The state is supported by a tunable interface arising from the oscillator's intrinsic number-dependent coupling in the Fock-state-lattice representation. We independently prepare the state at...
