Solitons, spatiotemporal chaos and synchronization in arrays of damped driven nonlinear oscillators
… weak disorder in the simplest form, a single impurity, into the chain. We describe how a long impurity can induce a pinned soliton to form and prevent spatiotemporal chaos, synchronizing the oscillators in the chain. Lastly we study chains with several impurities in various …

Untersuchung der elektronischen Struktur quasi-zweidimensionaler Einlagerungsverbindungen
… und Simulationen im Rahmen eines Single-Impurity-Anderson-Modells verglichen. Neben dem Einfluß unterschiedlicher Valenzelektronen der interkalierten Atome auf den Einlagerungsprozeß werden Fragen zum Lokalisierungsverhalten von 4f- und 5f-Zuständen und zu den Veränderungen in der …

Electronic thermal conductivity of superconducting lead-manganese, indium-manganese, and indium-chromium alloy films
… gap of the excited state assoociated with a single impurity) which was used earlier to explain tunneling measurements, is 0.55; this value is consistent with our data. For In-Mn, the value £ = 0.85 gives excellent agreement with our data. For In-Cr, o the results for one sample are consistent …

The study of many-electron systems
… and applied to physical systems. An Anderson single-impurity model Hamiltonian based calculation of the magnetic susceptibility is performed for YbN in the presence of crystal fields using an alteration of the Non-Crossing Approximation proposed by Zwicknagl et.al., incorporating parameters …

Electrical characterisation of defects in wide bandgap semiconductors.
… Admittance spectroscopy of the films finds a single impurity-related acceptor level. It is observed in theses experiments that admittance spectroscopy detects no traps that can be attributed to extended defects, despite the fact that the dislocations are well-known to be active recombination …

Transport properties of anisotropic superconductors
… qualitatively as one would expect if electron-impurity interactions were the dominant source of scattering. The experimental data on ultrasonic attenuation and thermal conduction in the superconducting phase of UPt3 do not behave as one would expect if the electron-impurity phase shift were …

Experimental and gyrokinetic studies of impurity transport in the core of Alcator C-Mod Plasmas
… and modeling tools, a comprehensive study of impurity transport was performed on Alcator C-Mod L-mode discharges. A new, multi-pulse laser blow-off system was designed and constructed to introduce trace amounts of non-recycling, non-intrinsic, impurities in the plasma edge. This system was …

Electronic structure of strongly correlated low-dimensional spin ½ systems: cuprates and vanadates
… we calculated the electronic spectrum of the single Zn impurity in CuO2 plane considered as a vacancy in Cu 3d states. The analytic solution for the states of different symmetry was obtained. Depending on the strength of perturbation induced by the impurity on the neighboring Cu ions, the …
