The subject of study are nanoelectronic devices operating at the time scale of picoseconds. In this context, ultrashort pulses with a few-electrons propagating in quasi one-dimensional quantum conductors have been studied using time-of-flight measurements. They show a complicated dependence of the pulse propagation velocity on the electrostatic potentials as well as on the geometry of the interferometer, which is not captured by usual theories. The goal of this project is to gain a microscopic understanding of the mechanism using state of the art simulation tools and further to develop these tools to make predictive simulations of the pulse propagation prior to the experiment.
- model the electronic system by a tight-binding approach
- extend exising tools to include interactions self-consistently
- perform numerical simulations in close relation with the experiments
- develop a simplified complementary approach, e.g. using Boltzmanns equation
The future candidate is expected to have strong knowledge of nanoelectronic and semiconductor devices and to be familiar with the theory of interacting and-time dependent manybody systems. Knowledge on tight-binding systems and Boltzmann kinetic theory would be an advantage. In addition to analytical skills, the applicant should have experience in numerical algorithm developement and parallel programming and contribute to the existing simulation tools (as Kwant/Tkwant) used in the group. The programming language of choice will be Python.
