  Tidal disruption events\,(TDEs) provide a valuable probe in studying the
dynamics of stars in the nuclear environments of galaxies. Recent observations
show that TDEs are strongly overrepresented in post-starburst or "green valley"
galaxies, although the underlying physical mechanism remains unclear.
Considering the possible interaction between stars and active galactic
nucleus\,(AGN) disk, the TDE rates can be greatly changed compared to those in
quiescent galactic nuclei. In this work, we revisit TDE rates by incorporating
an evolving AGN disk within the framework of the "loss cone" theory. We
numerically evolve the Fokker-Planck equations by considering the star-disk
interactions, in-situ star formation in the unstable region of the outer AGN
disk and the evolution of the accretion process for supermassive black
holes\,(SMBHs). We find that the TDE rates are enhanced by about two orders of
magnitude shortly after the AGN transitions into a non-active stage. During
this phase, the accumulated stars are rapidly scattered into the loss cone due
to the disappearance of the inner standard thin disk. Our results provide an
explanation for the overrepresentation of TDEs in post-starburst galaxies.
