Ultrafast melting and recovery of collective order in the excitonic insulator Ta2NiSe5
The dominant mechanism of the excitonic insulator transition in Ta2NiSe5 and the nature of its high-temperature phase are debated. The authors report transient reflectivity measurements indicating a significant electronic contribution to the transition and a gapped state of preformed excitons at hig...
