Strong interband interaction in the excitonic insulator phase of TaNiSe
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…

Temperature-dependent evolutions of excitonic superfluid plasma frequency in a srong excitonic insulator candidate, TaNiSe
Yu-Seong Seo, Man Jin Eom, Jun Sung Kim +3
We investigate an interesting anisotropic van der Waals material, TaNiSe, using optical spectroscopy. TaNiSe has been known as one of the few excitonic insu…
