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…
