DNA分子的电导：退相干和成键的影响
Conductance of DNA molecules: Effects of decoherence and bonding
摘要：
通过将最近开发的唯象统计模型（EPJB { \bf 68}，237（2009））拟合到实验结果来检查退相干和键合对单个双链DNA分子的线性电导的影响。DNA分子本身通过紧密结合梯形模型来描述，该模型具有从公开的从头计算获得的参数（J.Am.Chem.Soc. { \bf 127}，14894（2005））。与序列和长度依赖性实验的良好协议给出了一个提示的性质在DNA中的传导，并在同一时间提供了一个关键的测试模型。
英文摘要：
The influence of decoherence and bonding on the linear conductance of single double-stranded DNA molecules is examined by fitting a phenomenological statistical model developed recently (EPJB {\bf 68}, 237 (2009)) to experimental results. The DNA molecule itself is described by a tight binding ladder model with parameters obtained from published ab initio calculations (J.Am.Chem.Soc. {\bf 127}, 14894 (2005)). The good agreement with the experiments on sequence and length dependence gives a hint on the nature of conduction in DNA and at the same time provides a crucial test of the model.
