9974435MatveevThis grant will support theoretical research in the electronic properties of mesoscopic structures. Three primary focus areas will be emphasized: Coulomb blockade effects in quantum dots connected to external reservoirs by quantum dots, thermopower in coupled quantum dot systems, and spin-orbit interaction effects on the spin susceptibility of nanoparticles. Perturbation theory, bosonization techniques, and other theoretical approaches will be used in this work, which is expected to explain current experiments on nanoscale structures as well as stimulate new experiments. The theoretical findings can be tested using experiments on semiconductor heterostructures, metallic systems, and self-assembled structures.The main objective of this research grant is to advance our understanding of the behavior of electrons in nanostructures. The submicron scales of current electronic devices makes a theoretical understanding of such behavior technologically important for our overall understanding of new devices. This work is expected to explain current experimental results, as well as stimulate new experiments on nanoscale devices and materials. The theoretical findings of this work can be compared with experiments in semiconductor heterostructures, metallic systems, and self-assembled structures.

9974435matvev本基金将支持介观结构电子特性的理论研究。三个主要的重点领域将被强调：通过量子点连接到外部储层的量子点中的库仑封锁效应，耦合量子点系统中的热功率，以及自旋轨道相互作用对纳米粒子自旋磁化率的影响。微扰理论、玻色子化技术和其他理论方法将在这项工作中使用，这有望解释目前在纳米尺度结构上的实验，并激发新的实验。这些理论发现可以通过半导体异质结构、金属系统和自组装结构的实验来验证。这项研究的主要目的是促进我们对纳米结构中电子行为的理解。当前电子设备的亚微米尺度使得对这种行为的理论理解在技术上对我们对新设备的整体理解很重要。这项工作有望解释当前的实验结果，并激发纳米级器件和材料的新实验。本工作的理论发现可以与半导体异质结构、金属系统和自组装结构的实验结果进行比较。
