Grundzustandseigenschaften von anisotropen antiferromagnetischen Heisenberg-Ketten mit Spin S = 1
… functions and using a correspondence to Luttinger liquids one can distinguish commensurate and incommensurate regions of the spin liquid phase. For different parameters the spin liquid phase may be subdivided into regions of ferroquadrupolar and spin-density-wave ordering. Some of the …

Elektrischer Transport in Bündeln aus einwandigen Kohlenstoff-Nanoröhrchen mit semitransmissiven Kontakten
… predicted power laws based on the theory of Luttinger liquids and Coulomb blockade, respectively. Exponents ranging from 0.1 to 0.9 were extracted. In the frame of known theories a full description was not possible. Correlations between the barrier heights and the exponents are portended to a …

Strong correlations and topological order in one-dimensional systems
… disordered potentials is studied. The Tomonaga-Luttinger liquid (TLL), a model of interacting electrons in one spatial dimension, is considered in the context of two systems of experimental interest. First, a study of the electronic properties of single-walled armchair carbon nanotubes in the …

Functional renormalization group studies of quantum transport through mesoscopic systems
… interactions it belongs to the class of Luttinger liquids (LLs) whose low energy properties are characterized by power laws. The transport properties of LLs have been studied experimentally for example on carbon nanotubes. However, the presence of transport barriers at the contacts make …

Flussgleichungen zur Beschreibung statischer und dynamischer Eigenschaften des eindimensionalen Kondo-Gitter-Modells
… In diesem Bereich zeigt das Modell so genanntes Luttinger-Flüssigkeitsverhalten. Im Rahmen der Flussgleichungsmethode wird der Hamilton-Operator auf ein effektives Modell abgebildet, in dem Elektronen und Spinmomente vollständig entkoppelt sind. Das Resultat dieses Prozesses ist ein Modell, das …
