The shift towards clean energy brings about notable transformations to the energy system. In order to optimally plan a future energy system, it is necessary to consider the influence of several sectors as well as the interaction of the transmission g

In dieser Promotionsarbeit präsentiere ich die erstmalige Realisierung eines Zustands negativer absoluter Temperatur für bewegliche Teilchen, sowie zusätzlich die detaillierte Untersuchung der Dynamik eines Quantenphasenübergangs. Als Grundlage f

The preparation and reactivity of a range of model systems for the low temperature oxidation of CO by gold catalysts have been investigated with a view to assessing their feasibility for bridging the 'materials gap' between well-defined single crysta

In this comment we argue that negative absolute temperatures are a well-established concept for systems with bounded spectra. They are not only consistent with thermodynamics, but are even unavoidable for a consistent description of the thermal equil

We experimentally and numerically investigate the expansion of initially localized ultracold bosons in homogeneous one- and two-dimensional optical lattices. We find that both dimensionality and interaction strength crucially influence these non-equi

Absolute temperature, the fundamental temperature scale in thermodynamics, is usually bound to be positive. Under special conditions, however, negative temperatures - where high-energy states are more occupied than low-energy states - are also possib

We have experimentally studied few-body impurity systems consisting of a single fermionic atom and a small bosonic field on the sites of an optical lattice. Quantum phase revival spectroscopy has allowed us to accurately measure the absolute strength
