Optical Excitations of Flat Bands Induced by Exciton Condensation in TaPdTe
Shaohui Yi, Zhiyu Liao, Chenhao Liang +10
We report on the charge dynamics of TaPdTe using temperature-dependent optical spectroscopy with polarized light. We observe a metal-insulator transition characterized…
Axion insulator, Weyl points, quantum anomalous Hall effect and magnetic topological phase transition in Eu3In2As4
Jingyu Yao, Ruihan Zhang, Sheng Zhang +5
The magnetic topological phases attract much interest, such as the axion insulator, higher-order topology, Weyl semimetals, and the quantum anomalous Hall effect (QAHE). Here, we p…
Ta2Pd3Te5 topological thermometer
Yupeng Li, Anqi Wang, Senyang Pan +12
In recent decades, there has been a persistent pursuit of applications for surface/edge states in topological systems, driven by their dissipationless transport effects. However, t…
Layer-dependent Raman spectroscopy of ultrathin TaPdTe
Zhenyu Sun, Zhaopeng Guo, Dayu Yan +7
Two-dimensional topological insulators (2DTIs) or quantum spin Hall insulators are attracting increasing attention due to their potential applications in next-generation spintronic…
Excitonic Instability in Ta2Pd3Te5 Monolayer
Jingyu Yao, Haohao Sheng, Ruihan Zhang +7
By systematic theoretical calculations, we have revealed an excitonic insulator (EI) in the Ta2Pd3Te5 monolayer. The bulk Ta2Pd3Te5 is a van der Waals (vdW) layered compound, where…
Spontaneous gap opening and potential excitonic states in an ideal Dirac semimetal TaPdTe
Peng Zhang, Yuyang Dong, Dayu Yan +19
The opening of an energy gap in the electronic structure generally indicates the presence of interactions. In materials with low carrier density and short screening length, long-ra…
Evidence for an Excitonic Insulator State in TaPdTe
Jierui Huang, Bei Jiang, Jingyu Yao +30
The excitonic insulator (EI) is an exotic ground state of narrow-gap semiconductors and semimetals arising from spontaneous condensation of electron-hole pairs bound by attractive…
Observation of Emergent Superconductivity in the Quantum Spin Hall Insulator Ta2Pd3Te5 via Pressure Manipulation
Hui Yu, Dayu Yan, Zhaopeng Guo +13
Quantum Spin Hall (QSH) insulators possess distinct helical in-gap states, enabling their edge states to act as one-dimensional conducting channels when backscattering is prohibite…
