Thanks to modern technology it is nowadays possible to fabricate structures on the size of a few nanometers. In other words, thousands of these nanostructure fit into the diameter of single hair! For the dynamics of the particles in such structures a picosecond, which is a millionth of a millionth of a second, already feels like ages. In contrast to what we experience in everyday life, on these extreme scale new effects come into play, because everything is governed by the rules of quantum mechanics. These effects can be explored using laser pulses, which can also be used to control the dynamics in these system. To understand the new phenomena, a theoretical description and numerical modelling is required, which is the basis of our work.
We consider on the one hand nanostructures made of semiconductors, mostly semiconductor quantum dots, and on the other hand metallic structures, which act as antennas for visible light. Our simulations allow for predicting the dynamics and developing control schemes, which is a basic ingredient for applications in the field of quantum information technology.
Currently we work on:
