atoms are cooled down to temperatures of a few mK
and, at the same time, are excited to high-lying
internal states the typical order of time and
energy scales is turned upside down. Random,
thermal motion is overruled by the collective dance
of (quasi)particles, governed by their strong
interactions and correlations.
Such exotic types of matter are produced in several
laboratories and often appear in very different
states, ranging from fully-ionized ultracold
plasmas to so-called frozen Rydberg gases.
We aim at gaining theoretical insights into the
often complex dynamics of such gases. One of our
objectives is to exploit this understanding for a
selective manipulation and control of the system
Our research is driven by computational as well as
theoretical approaches and also benefits greatly
from close collaborations with leading experimental
groups in the field.
