Research Interests
|
One of
my interests is the manipulation of the internal states of Rydberg atoms
using electromagnetic pulses. The
main goal is the development
of 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. My
research interests are closely related to experimental developments and
involve fruitful collaboration with other scientists. |
