Spatial correlations of trapped 1d bosons in an optical lattice
C. Kollath, U. Schollwöck, J. von Delft +1
We investigate a quasi-one dimensional system of trapped cold bosonic atoms in an optical lattice by using the density matrix renormalization group to study the Bose-Hubbard model…

Mott-Hubbard transition of cold atoms in optical lattices
W. Zwerger
We discuss the superfluid to Mott-insulator transition of cold atoms in optical lattices recently observed by Greiner et.al. (Nature 415, 39 (2002)). The fundamental properties of…
