Cleavage-History-Dependent Low-Temperature ARPES Spectra of Charge-Ordered EuAl $_{4}$

Hao Liu, Bo Chen, Chen Zhang +9

Charge ordering in EuAl $_{4}$ has been widely discussed in connection with band reconstruction, magnetism, and topological electronic states, yet the microscopic origin of the comple…

Ultrafast Fluence-Reversal Fingerprint of Fragile Kondo Hybridization in CePt $_{2}$ In $_{7}$

Xin-Yi Tian, Qi-Yi Wu, Chen Zhang +13

The emergence of heavy quasiparticles in a Kondo lattice is usually viewed as the formation of a low-energy hybridization gap. Whether this gap represents a rigid electronic struct…

Electronic Nematicity Revealed by Polarized Ultrafast Spectroscopy in Bilayer La $_{3}$ Ni $_{2}$ O $_{7}$

Qi-Yi Wu, De-Yuan Hu, Chen Zhang +14

We report a polarized ultrafast pump-probe study of the normal-state electronic dynamics in bilayer La $_{3}$ Ni $_{2}$ O $_{7}$ and trilayer La $_{4}$ Ni $_{3}$ O $_{10}$ single crystals at ambient p…
