Doping-controlled transition from excitonic insulator to semimetal in TaNiSe
L. Chen, T. T. Han, C. Cai +4
Excitonic insulator (EI) is an intriguing insulating phase of matter, where electrons and holes are bonded into pairs, so called excitons, and form a phase-coherent state via Bose-…

Anomalous spectral weight transfer in the nematic state of iron-selenide superconductor
C. Cai, T. T. Han, Z. G. Wang +6
Nematic phase intertwines closely with high-Tc superconductivity in iron-based superconductors. Its mechanism, which is closely related to the pairing mechanism of superconductivit…

Momentum-resolved measurement of electronic nematic susceptibility in the FeSeS superconductor
C. Cai, T. T. Han, Z. G. Wang +6
Unveiling the driving force for a phase transition is normally difficult when multiple degrees of freedom are strongly coupled. One example is the nematic phase transition in iron-…
