Charge-density-wave instabilities driven by multiple umklapp scattering
Peter Schmitteckert, Ralph Werner
We show that the concept of umklapp-scattering driven instabilities in one-dimensional systems can be generalized to arbitrary multiple umklapp-scattering processes at commensurate…
Low temperature electronic properties of Sr_2RuO_4 III: Magnetic fields
Ralph Werner
Based on the microscopic model introduced previously the observed specific heat and ac-susceptibility data in the superconducting phase in Sr_2RuO_4 with applied magnetic fields ar…
Low temperature electronic properties of Sr_2RuO_4 II: Superconductivity
Ralph Werner
The body centered tetragonal structure of Sr_2RuO_4 gives rise to umklapp scattering enhanced inter-plane pair correlations in the d_{yz} and d_{zx} orbitals. Based on symmetry arg…
Low temperature electronic properties of Sr_2RuO_4 I: Microscopic model and normal state properties
Ralph Werner, V. J. Emery
Starting from the quasi one-dimensional kinetic energy of the d_{yz} and d_{zx} bands we derive a bosonized description of the correlated electron system in Sr_2RuO_4. At intermedi…
Orbital-singlet pairing and order parameter symmetry in Sr_2RuO_4
Ralph Werner
Based on the degeneracy of the d_{zx} and d_{yz} orbitals in Sr_2RuO_4 it is argued that the Cooper pairs condense in orbital singlets. Together with the spin-triplet wave function…
Line shapes of dynamical correlation functions in Heisenberg chains
Ralph Werner, Andreas Kluemper
We calculate line shapes of correlation functions by use of complete diagonalization data of finite chains and analytical implications from conformal field theory, density of state…
