Strong interband interaction in the excitonic insulator phase of Ta $_{2}$ NiSe $_{5}$

Jinwon Lee, Chang-Jong Kang, Man Jin Eom +3

Excitonic insulator (EI) was proposed in 60's as a distinct insulating state originating from pure electronic interaction, but its material realization has been elusive with extrem…
