  • Anyon Hubbard Model in One-Dimensional Optical Lattices 
    Greschner, Sebastian; Santos, Luis (College Park, MD : American Physical Society, 2015)
    Raman-assisted hopping may be used to realize the anyon Hubbard model in one-dimensional optical lattices. We propose a feasible scenario that significantly improves the proposal of T. Keilmann et al. [Nat. Commun. 2, 361 ...
  • Density-dependent synthetic gauge fields using periodically modulated interactions 
    Greschner, Sebastian; Sun, G.; Poletti, D.; Santos, Luis (College Park, MD : American Physical Society, 2014)
    We show that density-dependent synthetic gauge fields may be engineered by combining periodically modulated interactions and Raman-assisted hopping in spin-dependent optical lattices. These fields lead to a density-dependent ...
  • In situ spectroscopic ellipsometry as a pathway toward achieving VO2stoichiometry for amorphous vanadium oxide with magnetron sputtering 
    Xu, C.; Heinemeyer, F.; Dittrich, A.; Bäumer, C.; Reineke-Koch, R. (New York, NY : American Inst. of Physics, 2021)
    As a special class of materials, transition metal oxides exhibit in their crystalline phase a variety of interesting properties, such as metal-insulator transition, ferroelectricity, magnetism, superconductivity, and so ...
  • Ultracold bosons in zig-zag optical lattices 
    Greschner, Sebastian; Santos, Luis; Vekua, T. (College Park, MD : American Physical Society, 2013)
    Ultracold bosons in zig-zag optical lattices present a rich physics due to the interplay between frustration induced by lattice geometry, two-body interactions, and a three-body constraint. Unconstrained bosons may develop ...
