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…
Spin-Chiral Bulk Fermi Surfaces of BiTeI Proven by Quantum Oscillations
Joonbum Park, E. Kampert, Kyung-Hwan Jin +10
We present the Fermi-surface map of the spin-chiral bulk states for the non-centrosymmetric semiconductor BiTeI using de Haas-van Alphen and Shubnikov-de Haas oscillations. We iden…
Anisotropic Dirac fermions in a Bi square net of SrMnBi2
Joonbum Park, G. Lee, F. Wolff-Fabris +8
We report the highly anisotropic Dirac fermions in a Bi square net of SrMnBi2, based on a first principle calculation, angle resolved photoemission spectroscopy, and quantum oscill…
