Tamar Seideman of Northwestern University is supported by the Theoretical and Computational Chemistry and Materials Theory Programs to develop and apply quantum mechanical methods in understanding current-triggered dynamics in molecular-scale devices. This research will address effects due to both the electronic and nuclear degrees of freedom, and employs scattering methods to describe electron transport. Applications include modeling currents across electrodes and across tips in scanning tunneling microscopy experiments.Many new technologies are possible if molecular-scale electronic transport could be understood and controlled. The outcomes of this research will enhance fundamental understanding of conductance at the molecular level, explore new ways of manipulating matter at the nanometer scale, and potentially contribute to discoveries of new phenomena in the nanotechnology.

西北大学的塔玛·塞德曼（Tamar Seideman）得到了理论和计算化学和材料理论计划的支持，旨在开发和应用量子机械方法，以理解分子尺度设备中电流触发的动力学。 这项研究将解决由于电子自由度和核核度的影响，并采用散射方法来描述电子传输。 应用包括在扫描隧道显微镜实验中对电极进行建模电流和跨尖端。如果可以理解和控制分子尺度的电子传输，则可以进行许多新技术。 这项研究的结果将增强对分子水平的电导的基本理解，探索以纳米量表操纵物质的新方法，并有可能有助于纳米技术中新现象的发现。
