Strong long-wavelength electron-phonon coupling in TaNi(Se,S)
Zhibo Kang, Burak Gurlek, Weichen Tang +9
The search for intrinsic excitonic insulators (EI) has long been confounded by coexisting electron-phonon coupling in bulk materials. Although the ground state of an EI may be diff…
Anomalous excitonic phase diagram in band-gap-tuned Ta2Ni(Se,S)5
Cheng Chen, Weichen Tang, Xiang Chen +17
During a band-gap-tuned semimetal-to-semiconductor transition, Coulomb attraction between electrons and holes can cause spontaneously formed excitons near the zero-band-gap point,…
Role of electron-phonon coupling in excitonic insulator candidate Ta2NiSe5
Cheng Chen, Xiang Chen, Weichen Tang +15
Electron-hole bound pairs, or excitons, are common excitations in semiconductors. They can spontaneously form and ``condense'' into a new insulating ground state -- the so-called e…
Quantum oscillations in the non-centrosymmetric superconductor and topological nodal-line semimetal PbTaSe
Xitong Xu, Zhibo Kang, Tay-Rong Chang +6
We observed quantum oscillations in thermoelectric and magnetic torque signals in non-centrosymmetric superconductor PbTaSe. One oscillatory frequency stems from the orbits for…
