This study investigates real topological phonons in 3D carbon allotropes, focusing on their classification and identification in the Samara Carbon Allotrope Database (SACADA). By performing high-throughput calculations, the researchers identified 65 materials with a phononic real Chern insulating (PRCI) state, 2 with a phononic real nodal line (PRNL) state, 10 with a phononic real Dirac point (PRDP) state, and 8 with a phononic real triple-point pair (PRTPP) state. These states are characterized by nontrivial real topology, protected by space-time inversion symmetry (PT) and lacking spin-orbit coupling. The study highlights the potential of 3D carbon allotropes as a valuable framework for exploring topological phonons, including phononic hinge modes and real topological states. The research provides a comprehensive understanding of the real topology in 3D materials and expands the scope of topological phononic materials by identifying four distinct forms of real topological phononic states. The findings demonstrate the existence of clean topological boundary modes, such as phononic surface states (PSSs) and phononic hinge states (PHSs), in specific carbon allotropes. The study emphasizes the importance of 3D carbon allotropes in the exploration of fascinating physics related to phononic hinge modes and real topological phonons.This study investigates real topological phonons in 3D carbon allotropes, focusing on their classification and identification in the Samara Carbon Allotrope Database (SACADA).
