In this paper we introduce the log entropy functional and establish its monotonicity along the Ricci flow. One consequence of it is the monotonicity of the logarithmic Sobolev constant along the Ricci flow.

On Perelman's $W$-entropy and Shannon entropy power for super Ricci flows on metric measure spaces
The author proves W-entropy dissipation and Shannon entropy power concavity on closed (K,n,N)-super Ricci flows over metric measure spaces, and connects lower-bounded W-entropy to volume non-collapsing on RCD(0,N) spaces.
