Island formation and dynamics of gold clusters on amorphous carbon films
Ralph Werner, Matthias Wanner, Guenter Schneider +1
Samples of Au clusters deposited by laser ablation on an amorphous-carbon substrate are investigated. After a few months storage at room temperature the initially statistically dis…
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…
Excess current in superconducting SrRuO
F. Laube, G. Goll, M. Eschrig +2
We present results from point-contact measurements on SrRuO that show a linear dependence of the excess current as a function of temperature and applied magnetic fields ove…
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…
