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…

Magneto-elastic excitations in spin-Peierls systems
Michael Holicki, Holger Fehske, Ralph Werner
Within the random phase approximation to the spin-Peierls transition two parameter regimes of phonon softening and hardening are present. Magneto-elastic excitations are discussed…

Dynamical dimer-dimer correlation functions from exact diagonalization
Ralph Werner
A regularization method is presented to deduce dynamic correlation functions from exact diagonalization calculations. It is applied to dimer-dimer correlation functions in quantum…
