Research in my group is focussed on the development and the application of numerical techniques to investigate the quantum mechanical properties of nanoscopic systems. Carriers trapped within such structures exhibit strong quantum mechanical effects that are of fundamental interest to understand the properties of matter. Moreover, their unique properties can be exploited in the realm of nanotechnology. Our task is to develop theoretical concepts, implement them into computational methods and interpret experimental results; or provide genuine predictions.
Our theoretical description is based on ab-initio methods, where we describe the nanostructures atom by atom. This atomistic description allows us to accurately describe colloidal semiconductor clusters, made of a few hundred atoms, all the way to epitaxial quantum dots made of millions of atoms. Our calculations of correlated many-body wave functions lead to accurate optical properties. These are relevant in the modern fields of quantum information science and solid-state quantum optics.
Our research group is currently involved in the following funded projects:
In October 2015 Prof. Gabriel Bester and Dr. Peng Han were awarded with the HLRS Golden Spike Award for the presentation of their work in the field of Ab initio calculations of the vibrational properties and dynamical processes in semiconductor nanostructures.
