Quantum Coherent Transport in Atoms & Electrons
Online Presentations | 21 Jun 2017 | Contributor(s):: Yong P. Chen
I will discuss some recent experimental examples from my lab studying quantum coherent transport and interferometry in electrons as well as cold atoms. For example, phase coherent electron transport and interference around a cylinder realized in a nanowire of topological insulator...

NEMO5 and 2D Materials: Tuning Bandstructures, Wave Functions and Electrostatic Screening
Online Presentations | 19 Oct 2016 | Contributor(s):: Tillmann Christoph Kubis
In this talk, I will briefly discuss the MLWF approach and compare it to DFT and atomistic tight binding. Initial results using the MLWF approach for 2D material based devices will be discussed and compared to experiments. These results unveil systematic band structure changes as functions of the...
