Correlated bosons on a lattice: Dynamical mean-field theory for Bose-Einstein condensed and normal phases
Krzysztof Byczuk, Dieter Vollhardt
We formulate a bosonic dynamical mean-field theory (B-DMFT) which provides a comprehensive, thermodynamically consistent framework for the theoretical investigation of correlated l…

Exact many-electron ground states on the diamond Hubbard chain
Zsolt Gulacsi, Arno Kampf, Dieter Vollhardt
Exact ground states of interacting electrons on the diamond Hubbard chain in a magnetic field are constructed which exhibit a wide range of properties such as flat-band ferromagnet…
