Orbital-Selective Quasiparticle Depletion across the Density Wave Transition in Trilayer Nickelate La${}_4$Ni${}_3$O${}_{10}$

Dong-Hyeon Gim, Chung Ha Park, Kee Hoon Kim

We investigate the evolution of polarized electronic Raman response in trilayer nickelate La${}_4$Ni${}_3$O${}_{10}$, uncovering a systematic reduction of the incoherent electron continu…
