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

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 continuum across the density wave transition in the $A_{1 g}$ and $B_{1 g}$ representations. Analysis based on the Fermi surface band curvatures points to quasiparticle coherence in momentum positions with dominant $d_{x^{2} - y^{2}}$ orbital character. Our findings establish the symmetry channels and the active role of $d_{x^{2} - y^{2}}$ orbitals involved in the density wave formation, offering important insight into the electronic and magnetic correlations in the nickelate.
