| contents | 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 $A_{1g}$ and $B_{1g}$ 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. |
