WebNov 26, 2024 · The time-dependent correlation function C(t) is given by: C(t) = < A ( 0) A ( t) > < A ( 0) A ( 0) > = (f0, A(t)) = a0(t) (17) The basal coefficient a0(t) is just the time-dependent correlation function. The time-dependent coefficients aν(t) obey a second recurrence relation (RRII): Δν + 1aν + 1(t) = − ˙aν(t) + aν − 1(t) ν ≥ 0, (18) WebHohenberg, E. D. Siggia, and B. I.
