Spin textures, screening and excitations in dirty quantum Hall ferromagnets
S. Rapsch, J. T. Chalker, D. K. K. Lee
We study quantum Hall ferromagnets in the presence of a random electrostatic impurity potential. Describing these systems with a classical non-linear sigma model and using analytic…

Density matrix renormalization group for disordered bosons in one dimension
S. Rapsch, U. Schollwoeck, W. Zwerger
We calculate the zero-temperature phase diagram of the disordered Bose-Hubbard model in one dimension using the density matrix renormalization group. For integer filling the Mott i…
