Orbital-dependent modulation of the superconducting gap in uniaxially strained BaKFeAs
L. Chen, T. T. Han, C. Cai +4
Pairing symmetry which characterizes the superconducting pairing mechanism is normally determined by measuring the superconducting gap structure (). Here, we report the meas…
Metal-Insulator Transition and Emergent Gapped Phase in the Surface-Doped 2D Semiconductor 2H-MoTe
T. T. Han, L. Chen, C. Cai +4
Artificially created two-dimensional (2D) interfaces or structures are ideal for seeking exotic phase transitions due to their highly tunable carrier density and interfacially enha…
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-…
Isostructural spin-density-wave and superconducting gap anisotropies in iron-arsenide superconductors
T. T. Han, L. Chen, C. Cai +4
When passing through a phase transition, electronic system saves energy by opening energy gaps at the Fermi level. Delineating the energy gap anisotropy provides insights into the…
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…
