Flat bands, Dirac cones, and atom dynamics in an optical lattice
Flat bands, Dirac cones, and atom dynamics in an optical lattice
We study atoms trapped with a harmonic confinement in an optical lattice characterized by a flat band and Dirac cones. We show that such an optical lattice can be constructed which can be accurately described with the tight binding or Hubbard models. In the case of fermions the release of …
