英文摘要	Layered kagome metals AV3Sb5 (A = K, Rb, Cs) exhibit diverse correlated electron phenomena. They include charge density wave formation and superconductivity, the pairing symmetry of which, however, is controversial due to contradictory experimental evidence. Through calculations based on real-space lattice models at the meanfield level, we investigate the vortex and surface spectra of all competitive pairing propensities suggested for AV3Sb5 from a weak-coupling analysis of unconventional superconductivity. Chiral p-wave pairing emerges as the only option to host Majorana bound states in the vortex core. We find chiral edge states for both p-wave and d-wave pairing, along with flat Andreev surface bound states for f-wave pairing. Our results expand the fingerprint of superconducting pairing and thus will contribute to resolving the nature of superconductivity in AV3Sb5.
