Figure 2 |   Robust QD-cavity interaction in a topological bulk cavity. a Simulated Purcell factor of bulk state versus emission wavelength (red dots). The PL spectrum of bulk state from Fig. 2c is also shown for comparison (black curve). Inset: Simulated radiation field (|E|2) from a single emitter coupled to bulk state. b Simulated Purcell factor of bulk state versus source position (red dots) and the corresponding electric field intensity distribution (black curve). c The measured radiative lifetimes of XX photons from QD1 and QD2 coupled to topological bulk cavities (red) compared to the lifetimes of XX photons from QDs in slab (blue). d Left panel: Time-resolved XX photon counts of QD1, QD2 and a QD in slab (indicated by green arrow). Right panel: Position of QD1 and QD2 in relative to the topological bulk cavity.
