Research Group of Prof. Dr. Bester
Theory of Nanoscopic Systems
Research in our 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 group is associated with Physics Department (INF).
Our research group is currently involved in the following funded projects:
- ITN Project 4Photon
- DFG Project Resonant Raman spectroscopy as tool to investigate colloidal semiconductor nanocrystals
- Cluster of Excellence CUI: Advanced Imaging of Matters
HLRS Golden Spike Award
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 vibration characteristics and dynamic processes in semiconductor nanostructures.
Preis für gute Lehre (Award for Good Teaching)
In April 2019, Prof. Gabriel Bester was awarded with the 2nd prize for good teaching for his lecture "Quantenphysik/-chemie", in the category "Lectures in Winter Semester 2018/2019", by student representatives of the Physics Department (Universität Hamburg).
