Multipartite entanglement serves as a faithful detector for quantum phase transitions
We investigate quantum phase transitions (QPTs) in various spin chain systems using the multipartite entanglement measure $ au_mathrm{SEF}$ based on the monogamy inequality of squared entanglement of formation (EOF).Our results demonstrate that $ au_mathrm{SEF}$ is more effective and reliable than bipartite entanglement or bipartite correlation mea
