Multi-band Gutzwiller wave functions for itinerant ferromagnetism
Joerg Buenemann, Florian Gebhard, Werner Weber
Multi-band Gutzwiller-correlated wave functions reconcile the contrasting concepts of itinerant band electrons versus electrons localized in partially filled atomic shells. The app…

Thermodynamics of the low-temperature structural transition in rare-earth-doped La_{2-x}Sr_xCuO_4
Ralph Werner, M. Hücker, B. Büchner
The Sr concentration dependence of the structural transition from the orthorhombic into the tetragonal low-temperature phase in rare-earth-doped (R = Nd, Eu) La_{2-x-y}Sr_xR_yCuO_4…

The 1/2-XXZ spin-chain at finite magnetic field: Crossover phenomena driven by temperature
A. Klümper, J. R. Reyes Martínez, C. Scheeren +1
We investigate the asymptotic behaviour of spin-spin correlation functions for the integrable Heisenberg chain. To this end we use the Quantum Transfer Matrix (QTM) technique devel…
