Polymer-Defined Semiconductor Nanostructures, "top-down" approach, either micelles formed by diblock-copolymers or other self-assembled patterns like "breath figures" or imprints of colloids in polymer films are used for the formation of metal masks of different sizes on semiconductors in a first preparation step. These metal masks are then us

Electron Coherence in Mesoscopic Kondo Wires, phase coherence time extracted from the weak antilocalisation shows a pronounced plateau in a temperature region of . mK - . mK, associated with the phase breaking due to the Kondo effect. Below the Kondo temperature, the phase coherence time increases, as expected in the framework of Kondo physics

Scaling of the Quantum Hall Plateau Transition,ependence in the variable-range hopping regime allow to determine the localization length ξ, confirming the predicted scaling behavior ξ ∝ |B-B.|. with a universal critical exponent γ=2.3±0.2. For devices of reduced size we observe conductance fluctuations at the plateau transition. Their temperatur

Real-Space Renormalization and Energy-Level Statistics at the Quantum Hall Transition,ied to the Chalker-Coddington network model, reproduces the critical distribution of the . transmission coefficients, i.e., two-terminal conductances, P.(G), with very high accuracy. The RG flow of . at energies away from the transition yields a value of the critical exponent, ν.=2.39±0.01, that agr

LDA+DMFT Investigations of Transition Metal Oxides and f-Electron Materials, mean-field theory (DMFT) has been proven to be a powerful tool for the realistic modeling of strongly correlated electron systems. This paper provides a brief introduction to this novel computational technique and presents the results for two prime examples of strongly correlated electron systems,
