We investigate quantum phase transitions (QPTs) in various spin chain systems using the multipartite entanglement measure $\tau_\mathrm{SEF}$ based on the monogamy inequality of squared entanglement of formation (EOF). Our results demonstrate that $\tau_\mathrm{SEF}$ is more effective and reliable than bipartite entanglement or bipartite correlation measures such as EOF. von Neumann e... https://www.roneverhart.com/
