Effect of the exchange hole on the Gutzwiller approximation in one dimension
Balazs Hetenyi, Hans Gerd Evertz, Wolfgang von der Linden
The Gutzwiller approximate solution to the Gutzwiller wavefunction yields exact results for the Gutzwiller wavefunction in the infinite dimensional limit. Implicit in the Gutzwille…

Excitation spectra of strongly correlated lattice bosons and polaritons
Peter Pippan, Hans Gerd Evertz, Martin Hohenadler
Spectral properties of the Bose-Hubbard model and a recently proposed coupled-cavity model are studied by means of quantum Monte Carlo simulations in one dimension. Both models exh…
