  • Adiabatic spin cooling using high-spin Fermi gases 
    Colomé-Tatché, Maria; Klempt, Carsten; Santos, Luis; Vekua, Teimuraz (Bristol : IOP Publishing Ltd., 2011)
    Spatial entropy redistribution plays a key role in adiabatic cooling of ultra-cold lattice gases. We show that high-spin fermions with a spatially variable quadratic Zeeman coupling may allow for the creation of an inner ...
  • 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 ...
  • Dissipative preparation of antiferromagnetic order in the Fermi-Hubbard model 
    Kaczmarczyk, J.; Weimer, Hendrik; Lemeshko, Mikhail (Bristol : Institute of Physics Publishing, 2016)
    The Fermi-Hubbard model is one of the key models of condensed matter physics, which holds a potential for explaining the mystery of high-temperature superconductivity. Recent progress in ultracold atoms in optical lattices ...
  • 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 ...
