Inhomogeneously doped two-leg ladder systems
Stefan Wessel, Martin Indergand, Andreas Laeuchli +2
A chemical potential difference between the legs of a two-leg ladder is found to be harmful for Cooper pairing. The instability of superconductivity in such systems is analyzed by…

Phase Diagram of the quadrumerized Shastry-Sutherland Model
Andreas Laeuchli, Stefan Wessel, Manfred Sigrist
We determine the phase diagram of a generalized Shastry-Sutherland model, using a combination of dimer- and quadrumer-boson methods and numerical exact diagonalization techniques.…
