- W2080499142 abstract "The exact solution for a transition probability in vibrationally modulated electron transfer is found by employing three independent methods based on: (a) a path integral technique, (b) direct diagonalization of the Hamiltonian by a unitary transformation, and (c) Keldysh–Green’s function techniques. We also consider a solution in the noninteracting blip approximation (NIBA). The comparative analysis reveals that the NIBA is valid at longer times, small reorganization energy, high temperatures, and for small transition matrix elements, Δ0, while at large Δ0 the NIBA provides relaxation rates as much as twice greater. When Δ0=0, the NIBA transition probability difference oscillates in time with the frequency ∼ErkT/ℏ2 exhibiting incorrect behavior. At low temperatures, the exact solution yields power-law evolution. The NIBA solution exhibits incorrect behavior at small values of Δ0. At larger transition matrix elements, the NIBA practically yields a correct description, i.e. the decay in accordance with the exact solution while the coherent oscillations reveal some phase shift at longer times. An important case of several mode modulation is also studied. The Fourier analysis of the transition probability provides useful information of the vibrational couplings and frequencies. In general, the Fourier spectrum of the transition probability is the sum of the contributions from the harmonics with the frequencies |Δ0+∑i=0n(±)kiωi|(ki=0,1,2,3,…), where ωi is a modulating frequency. Thus, a generally used assumption about coincidence of coherence and vibrational frequencies appears to be incorrect." @default.
