The precision of matter-wave sensors benefits from interrogating large-particle-number atomic ensembles at high cycle rates. Quantum-degenerate gases with their low effective temperatures allow for constraining systematic ...

Evaporated Al as metallization for silicon solar cells may be profitable as it requires less Al material than the common screen-printed Al/Ag-paste combinations and forms contacts with a lower contact resistivity. To achieve ...

Ultracold potassium is an interesting candidate for quantum technology applications and fundamental research as it allows controlling intra-atomic interactions via low-field magnetic Feshbach resonances. However, the ...

Ziel der vorliegenden Arbeit ist die experimentelle Untersuchung des thermohydraulischen Verhaltens bei der Verdampfung und Kondensation in Plattenwärmeübertragern mit unterschiedlicher Oberflächenbeschaffenheit. Für die ...
