Description

Our research group is specialized in the use of numerical methods to treat atomic many-body systems with a high degree of sophistication. When necessary this is done in a relativistic framework and we are able to handle the additional complication of resonant states. Our approach is to continuously develop and adjust our methods to be able to address new challenging problems where our abilities are of special importance. We work often in close collaboration with experimental groups. The application concerns several subfields; 1) The Interaction of short electromagnetic pulses with atomic systems, where we concentrate on the effects of resonances on the one hand and on relativistic effects (the time-dependent Dirac-equation) on the other hand. The latter is motivated by the coming X-ray free electron lasers with extreme pulse intensities. 2) Quantum dots (semi-conductor devices that can be described as artificial atoms) where we work on the development of many-body methods to use on two-dimensional quantum dots to investigate their properties and dynamic response, as well as how these can be tailored. 3) Electron-ion recombination, where we want to continue our successful program, focusing now on calculations on complicated systems with many open shells. We collaborate with experimental groups around TSR (Heidelberg), around the Stockholm EBIT and around the future FAIR program at GSI. The common theme in all our projects is the need for accurate many-body calculations.
