Electronic Transport through Nanoscale Constrictions
A unique method for efficient calculations of the electronic transport properties of finite elongated nanoscale systems is being developed in our group. Based on density functional theory combined with a carefully designed divide-and-conquer computational approach, we have been able to predict the electronic properties and transport through micrometer long molecules such as trans-polyacetylene, carbon nanotubes, and graphene nanoribbons. Further development to include finite two-dimensional structures is being pursued.

Electron and Spin Dynamics in open systems
Time-domain simulation of electron dynamics in open systems is important for studying transient effects and transport mechanisms in molecular electronic devices. Based on time-dependent density-functional theory, a code is being developed, where efficient representation of the open system allows for the real-time simulation of electron dynamics in realistic molecular junction geometries.
