摘要：
We propose a novel parameterized entanglement measure alpha-concurrence for bipartite systems. By employing positive partial transposition and realignment criteria, we derive analytical lower bounds for the alpha-concurrence. Moreover, we calculate explicitly the analytic expressions of the alpha-concurrence for isotropic states and Werner states.
