Research Interests
|
One of my interests is the manipulation
of the internal states of Rydberg atoms using electromagnetic pulses. The main goal of this line of research is to develop control protocols
for producing and probing coherent states.
Control of physical phenomena promises to open up new fields of
research (e.g. information storage and retrieval) and to lead to the creation
of new techniques for exploration.
Physically, however, coherent states of atoms are destroyed for very long times due to the interaction of the
Rydberg atoms with the environment.
This brings me to my second research interest, namely the time
development of open quantum systems.
The decoherence of Rydberg states is mostly caused by the interaction
with other atoms or molecules, the radiative decay of the atom (spontaneous
emission), and the interactions with stray electromagnetic fields. One ultimate goal is to be able to simulate
these sources of decoherence as exactly as possible. Another goal is to study the
transition from quantum to classical dynamics as the quantum system interacts
with its environment and decoherence sets in.
Finally, my third research interest is
the interaction of ions with solids and surfaces. In this case, the main goal is to obtain
some understanding of electronic (charge transfer and ionization) and
chemical processes occurring during such interactions. One can exploit this knowledge base to
probe and modify solid surfaces. For
slow ions this subject represents an extremely complex many-body problem and provides
by far the most challenges in terms of accurate theoretical treatment. As can be inferred from my publications,
work within all my research interests is closely related to experimental
developments and involves many fruitful collaborations with other scientists. |
