  "abstract": "Searching for new mechanisms of $CP$ violation beyond the Standard Model is essential to explain the observed matter-antimatter asymmetry of the universe. By analyzing the full angular distribution of the quantum-entangled $Λ\\barΛ$ pairs from $J/ψ$ decays, the preliminary sensitivity of $CP$ asymmetry parameter $A_{CP}$ and Electric Dipole Moment of $Λ$ is studied at the future Super Tau-Charm Facility (STCF). Based on $3.4 \\times 10^{12}$ $J/ψ$ events at STCF, the projected sensitivity for $A_{CP}^Λ$ reaches the $10^{-4}$ level, while the $Λ$ EDM can be probed at $10^{-20}$ $e$ cm. These results highly indicate that STCF will provide an unprecedented opportunity to search for new mechanisms of $CP$ violation with an expected world-leading precision.",
