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. |
