  • Adsorbate induced refacetting: Pb chains on Si(557) 
    Czubanowski, M.; Schuster, A.; Akbari, S.; Pfnür, Herbert; Tegenkamp, Christoph (Bristol : IOP Publishing Ltd., 2007)
    The structure on the atomic and mesoscopic scale of Pb adsorbed on Si(557) has been investigated by high-resolution low energy electron diffraction (SPA-LEED). Depending on Pb coverage in the range between 1.2 and 1.6 ...
  • High-temperature superconductivity in the two-dimensional t-J model: Gutzwiller wavefunction solution 
    Kaczmarczyk, Jan; Buenemann, Joerg; Spalek, Jozef (Bristol : IOP Publishing Ltd., 2014-07-14)
    A systematic diagrammatic expansion for Gutzwiller wavefunctions (DE-GWFs) proposed very recently is used for the description of the superconducting (SC) ground state in the two-dimensional square-lattice t–J model with ...
  • Quantum stability of Mott-insulator states of ultracold atoms in optical resonators 
    Larson, Jonas; Fernandez-Vidal, Sonia; Morigi, Giovanna; Lewenstein, Maciej (Bristol : IOP Publishing Ltd., 2008)
    We investigate a paradigm example of cavity quantum electrodynamics with many body systems: an ultracold atomic gas inside a pumped optical resonator, confined by the mechanical potential emerging from the cavity-field ...
