Ultrafast Fluence-Reversal Fingerprint of Fragile Kondo Hybridization in CePtIn
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…
Nonthermal melting and density wave instability coupled to the lattice in LaNiO
Chen Zhang, Lixing Chen, Qi-Yi Wu +15
The recent discovery of high-temperature superconductivity in pressurized nickelates has renewed interest in the broken-symmetry states of their ambient-pressure parent phases, whe…
Energy-Resolved Real-Space Imaging of Orbital Nematicity in an Fe-Based Superconductor
Asato Onishi, Zifan Xu, Cédric Bareille +7
Electronic nematicity in Fe-based superconductors is manifested by spontaneous rotational symmetry breaking and the formation of nematic domains with mutually orthogonal directions…
Absence of Acoustic Phonon Anomaly in a Kagome Metal with Short-ranged Structural Modulation
Weiliang Yao, Supeng Liu, Zifan Xu +9
Kagome lattice VSb ( = K, Rb, and Cs) superconductors without magnetism from vanadium -electrons are intriguing because they have a novel charge density wave (CDW)…
