    Bacterial spores have a strong resistance to both chemical and physical hurdles and create a risk for food industry which has been tackled by applying high thermal intensity treatments to sterilize food. These strong thermal ...
  • Ultra-Dilute Gas of Polarons in a Bose–Einstein Condensate 
    Ardila, Luis A. Peña (Basel : MDPI, 2022)
    We investigate the properties of a dilute gas of impurities embedded in an ultracold gas of bosons that forms a Bose–Einstein condensate (BEC). This work focuses mainly on the equation of state (EoS) of the impurity gas ...

    Kirk, Ansgar T.; Bohnhorst, Alexander; Raddatz, Christian-Robert; Allers, Maria; Zimmermann, Stefan (Berlin ; Heidelberg : Springer, 2019)
    With recent advances in ionization sources and instrumentation, ion mobility spectrometers (IMS) have transformed from a detector for chemical warfare agents and explosives to a widely used tool in analytical and bioanalytical ...
  • Ultra-low vibration closed-cycle cryogenic surface-electrode ion trap apparatus 
    Dubielzig, Timko (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2021)
    Trapped ions are one of the leading platforms for building scalable quantum information processors. Current ion traps run on less than 100 qubits. A useful quantum computer needs to operate thousands or even millions of ...
