Imaging the coherent propagation of collective modes in the excitonic insulator Ta(2)NiSe(5) at room temperature
Excitonic insulators host a condensate of electron-hole pairs at equilibrium, giving rise to collective many-body effects. Although several materials have emerged as excitonic insulator candidates, evidence of long-range coherence is lacking and the origin of the ordered phase in these systems remai...
