  • 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 ...
  • Exploring unconventional hubbard models with doubly modulated lattice gases 
    Greschner, Sebastian; Santos, Luis; Poletti, D. (College Park, MD : American Physical Society, 2014)
    Recent experiments show that periodic modulations of cold atoms in optical lattices may be used to engineer and explore interesting models. We show that double modulation combining lattice shaking and modulated interactions ...
