Ground state phase diagram of the repulsive SU(3) Hubbard model in Gutzwiller approximation
Akos Rapp, Achim Rosch
We perform a variational Gutzwiller calculation to study the ground state of the repulsive SU(3) Hubbard model on the Bethe lattice with infinite coordination number. We construct…

Interacting Fermionic Atoms in Optical Lattices Diffuse Symmetrically Upwards and Downwards in a Gravitational Potential
Stephan Mandt, Akos Rapp, Achim Rosch
We consider a cloud of fermionic atoms in an optical lattice described by a Hubbard model with an additional linear potential. While homogeneous interacting systems mainly show dam…
