Dear David,

Thanks for your answer.
But I get the definition of correlation from our text book, Molecular
Modeling Principles and Applications by Andrew R. Leach. And it's just the
same as Pearson correlation (or at least the mathematical form). I have
attached a screenshot of the definition to this letter.

No: the "time correlation" [C(t)] is unreleated to the Pearson (linear)
correlation function (which it sounds like you might be thinking of).
C(t) is normalized such that C(0)=1; it is not the square of anything.

Apologies if I am misunderstanding your question.
