In this paper, we prove logarithmic Sobolev inequalities and derive the Hamilton Harnack inequality for the heat semigroup of the Witten Laplacian on complete Riemannian manifolds equipped with -super Perelman Ricci flow. We establish the -entropy formula for the heat equation of the Witten Laplacian and prove a rigidity theorem on complete Riemannian manifolds satisfying the condition, and extend the -entropy formula to time dependent Witten Laplacian on compact Riemannian manifolds with -super Perelman Ricci flow, where and are two constants. Finally, we prove the Li-Yau and the Li-Yau-Hamilton Harnack inequalities for positive solutions to the heat equation associated to the time dependent Witten Laplacian on compact or complete manifolds equipped with variants of the -super Ricci flow.
