用约化密度矩阵方法研究了DNA中的还原电子转移。对于DNA中的还原性电子转移，电子供体连接到DNA。当前的研究中明确描述了超短激光脉冲对该供体的光激发，以及电子从供体到受体的转移。此外，研究了附加桥分子的作用。所有这些研究都是使用三种不同的量子主方程进行的：一个马尔可夫方程和两个非马尔可夫方程，它们来自于时间局域或时间非局域形式主义。这三种不同的方法所造成的偏差进行了讨论。
Reductive electron transfer in DNA is investigated using the reduced density matrix formalism. For reductive electron transfer in DNA an electron donor is attached to the DNA. The photo-excitation of this donor by ultrashort laser pulses is described explicitly in the current investigation, as well as the transfer of the electron from the donor to the acceptor. In addition, the effect of an additional bridge molecule is studied. All these studies are performed using three different quantum master equations: a Markovian one and two non-Markovian ones derived from either a time-local or a time-nonlocal formalism. The deviations caused by these three different approaches are discussed.
