Optical Excitations of Flat Bands Induced by Exciton Condensation in Ta $_{2}$ Pd $_{3}$ Te $_{5}$

Shaohui Yi, Zhiyu Liao, Chenhao Liang +10

We report on the charge dynamics of Ta $_{2}$ Pd $_{3}$ Te $_{5}$ using temperature-dependent optical spectroscopy with polarized light. We observe a metal-insulator transition characterized…

Spectroscopic signatures of magnetization-induced band renormalization and strong spin-charge-lattice coupling in EuZn $_{2}$ As $_{2}$

Zhiyu Liao, Boxuan Li, Shaohui Yi +9

We report an infrared spectroscopy study of the antiferromagnetic (AFM) insulator EuZn $_{2}$ As $_{2}$ over a broad frequency range, spanning temperatures both above and below the AFM tr…
