Interaction induced collapse of a section of the Fermi sea in in the zig-zag Hubbard ladder

Kay Hamacher, Claudius Gros, Wolfgang Wenzel

Using the next-nearest neighbor (zig-zag) Hubbard chain as an one dimemensional model, we investigate the influence of interactions on the position of the Fermi wavevectors with th…

Disorder Induced Quantum Phase Transition in Random-Exchange Spin-1/2 Chains

K. Hamacher, J. Stolze, W. Wenzel

We investigate the effect of quenched bond-disorder on the anisotropic spin-1/2 (XXZ) chain as a model for disorder induced quantum phase transitions. We find non-universal behavio…
