Description
In this work, we discuss the impact of phase transitions on quark spin fluctuation and correlation. We propose a novel observable for quark-antiquark correlation that relates to vector meson spin alignment and $\Lambda-\bar\Lambda$ correlation. Using the NJL model, we qualitatively study the properties of quark-antiquark spin correlation. Our findings reveal a peak structure near the CEP, which could serve as an experimental signature of the CEP and explain the non-monotonic behavior of $\phi$ meson alignment at low collision energies.
