In this note we revisit the emergent conformal symmetry in near-ring region of warped spacetime. particular, propose a novel construction $sl(2,R)_{\text{QNM}}$ symmetry. We show that each eikonal QNM family falls into one highest-weight representation algebra, and can be related to isometry group $sl(2,R)_{\text{ISO}}$ simple way. Furthermore find coherent state space identified with phase pho...
