  • Active tailstock for precise alignment of precision forged crankshafts during grinding 
    Denkena, Berend; Gümmer, Olaf (Amsterdam : Elsevier, 2013)
    Within the Collaborative Research Centre 489 at the Leibniz Universitaet Hannover a new and innovative process chain for the manufacture of crankshafts is being investigated. By burr-free and near-net-shaped precision ...
  • Antiferromagnetic heisenberg spin chain of a few cold atoms in a one-dimensional trap 
    Murmann, S.; Deuretzbacher, Frank; Zürn, G.; Bjerlin, J.; Reimann, S.M.; Santos, Luis; Lompe, T.; Jochim, S. (College Park, MD : American Physical Society, 2015)
    We report on the deterministic preparation of antiferromagnetic Heisenberg spin chains consisting of up to four fermionic atoms in a one-dimensional trap. These chains are stabilized by strong repulsive interactions between ...
  • Approach for Increasing the Resource Efficiency for the Production Process of Titanium Structural Components 
    Denkena, Berend; Jacob, Stefan (Amsterdam : Elsevier, 2015)
    Titanium structural components for the aircraft industry are usually manufactured from ingots of primary material. The process chain for the fabrication of these components consists of the production of titanium sponge, ...
  • Influence of various irradiance models and their combination on simulation results of photovoltaic systems 
    Hofmann, Martin; Seckmeyer, Gunther (Basel : MDPI AG, 2017)
    We analyze the output of various state-of-The-Art irradiance models for photovoltaic systems. The models include two sun position algorithms, three types of input data time series, nine diffuse fraction models and five ...
  • Mechanical properties of co-extruded aluminium-steel compounds 
    Thürer, Susanne Elisabeth; Uhe, Johanna; Golovko, Oleksandr; Bonk, Christian; Bouguecha, Anas; Behrens, Bernd-Arno; Klose, Christian (Pfaffikon : Scientific.Net, 2017)
    Within the scope of the Collaborative Research Centre (CRC) 1153 novel process chains for the production of hybrid solid components by Tailored Forming are developed at the Leibniz Universität Hannover. The combination of ...
  • Molecular dynamics study of an amorphous polyethylene/silica interface with shear tests 
    Zhuang, Xiaoying; Zhou, Shuai (Basel : MDPI AG, 2018)
    An amorphous polyethylene/silica (PE/S) interface exists in many materials. However, the research of the interfacial properties at microscale is lacking. Shear failure and adhesion properties of an amorphous PE/S interface ...
  • Momentum distributions and numerical methods for strongly interacting one-dimensional spinor gases 
    Deuretzbacher, Frank; Becker, D.; Santos, Luis (College Park, MD : American Physical Society, 2016)
    One-dimensional spinor gases with strong δ interaction fermionize and form a spin chain. The spatial degrees of freedom of this atom chain can be described by a mapping to spinless noninteracting fermions and the spin ...
  • Multi-Provider Service Chain Embedding With Nestor 
    Dietrich, David; Abujoda, Ahmed; Rizk, Amr; Papadimitriou, Panagiotis (Piscataway, NJ : Institute of Electrical and Electronics Engineers Inc., 2017)
    Network function (NF) virtualization decouples NFs from the underlying middlebox hardware and promotes their deployment on virtualized network infrastructures. This essentially paves the way for the migration of NFs into ...
  • Optical Trapping of Ion Coulomb Crystals 
    Schmidt, Julian; Lambrecht, Alexander; Weckesser, Pascal; Debatin, Markus; Karpa, Leon; Schaetz, Tobias (College Park, Md. : APS, 2018)
    The electronic and motional degrees of freedom of trapped ions can be controlled and coherently coupled on the level of individual quanta. Assembling complex quantum systems ion by ion while keeping this unique level of ...
  • Quantum magnetism without lattices in strongly interacting one-dimensional spinor gases 
    Deuretzbacher, Frank; Becker, D.; Bjerlin, J.; Reimann, S.M.; Santos, Luis (College Park, MD : American Physical Society, 2014)
    We show that strongly interacting multicomponent gases in one dimension realize an effective spin chain, offering an alternative simple scenario for the study of one-dimensional (1D) quantum magnetism in cold gases in the ...
  • Spin-chain model for strongly interacting one-dimensional Bose-Fermi mixtures 
    Deuretzbacher, Frank; Becker, D.; Bjerlin, J.; Reimann, S.M.; Santos, Luis (College Park, MD : American Physical Society, 2017)
    Strongly interacting one-dimensional (1D) Bose-Fermi mixtures form a tunable XXZ spin chain. Within the spin-chain model developed here, all properties of these systems can be calculated from states representing the ordering ...
  • Theoretical study of the electronic states of hollandite vanadate K 2V8O16 
    Horiuchi, S.; Shirakawa, T.; Ohta, Y. (Bristol : IOP Publishing Ltd., 2009)
    Electronic states of hollandite vanadate K2V8O 16, a one-dimensional zigzag-chain system of t2g orbitals in a mixed valent state, are considered. We calculate the Madelung energies to determine the most stable charge-ordering ...
