Extensions of the Standard Model often predict new chiral interactions fortop quark, which will contribute to top quark spin correlation and polarizationin $t\bar{t}$ production at the LHC. In this work, under the constraints fromthe current Tevatron measurements, a comparative study of the spin correlationand polarization is performed in three new physics models: the minimalsupersymmetric model without R-parity (RPV-MSSM), the third-generation enhancedleft-right model and the axigluon model. We find that the polarizationasymmetry may be enhanced to the accessible level in all these models while thecorrection to the spin correlation may be detectable in the axigluon model andthe RPV-MSSM with $\lambda"$ couplings.
