Spectral Visualization of Excitonic Pair Breaking at Individual Impurities in Ta2Pd3Te5
Lianzhi Yang, Deguang Wu, Hanbo Zhang +9
Excitonic insulators host the condensates of bound electron-hole pairs, offering a platform for studying correlated bosonic quantum states. Yet, how macroscopic coherence emerges f…
Magnetotransport and Carrier Dynamics in Quasi-One-Dimensional Antiferromagnet KMnBi
Qi-Yuan Liu, Chenfei Shi, Zhaodi Lin +6
Quasi-one-dimensional materials MnBi ( = Na, K, Rb, Cs) exhibit unique electronic behaviors such as antiferromagnetism, charge density waves, and pressure-induced sup…
Quasi-linear magnetoresistance and paramagnetic singularity in Hypervalent Bismuthide
Zhongchen Xu, Yi Yan, Zhihao Liu +7
Materials featuring hypervalent bismuth motifs have generated immense interest due to their extraordinary electronic structure and exotic quantum transport. In this study, we synth…
Magnetic-Field Control of Tomonaga-Luttinger Liquids in Ta2Pd3Te5 Edge States
Xingchen Guo Anqi Wang, Xiutong Deng, Yupeng Li +12
Ta2Pd3Te5 is a quasi-one-dimensional transition-metal telluride whose heavy atoms endow the material with strong spin-orbit coupling, while the Fermi level inside the bulk gap make…
Crystalline electric field excitations in Weyl semimetal \textit{R}AlSi (\textit{R} = Ce, Pr and Nd)
Lin Yang, Yili Sun, Xiutong Deng +17
The rare earth intermetallic system \textit{R}Al\textit{X} (\textit{R} = rare earth elements, \textit{X} = Si and Ge) is known to be a promising candidate of magnetic Weyl semimeta…
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…
