    Group Delay in THz Spectroscopy with Ultra-Wideband Log-Spiral Antennae

    We report on the group delay observed in continuous-wave terahertz spectroscopy based on photomixing with phase-sensitive homodyne detection. We discuss the different contributions of the experimental setup to...

    Retraction Note: Evidence for spin–charge separation in quasi-one-dimensional organic conductors

    Nature 418, 614–617 (2002) In this Letter, we described the anomalous behaviour of the thermal conductivity k in quasi-one-dimensional Bechgaard salts. As we have since observed a conventional temperature depe...

    Evidence for spin–charge separation in quasi-one-dimensional organic conductors

    Interacting conduction electrons are usually described within Fermi-liquid theory1, which states that, in spite of strong interactions, the low-energy excitations are electron-like quasiparticles with charge and ...

    Experimental quest for orbital waves

    One challenge in condensed-matter physics is the experimental confirmation of a new kind of elementary excitation — orbital waves, or orbitons, which are predicted to exist in an orbitally ordered state. Saitoh e...

    An Ontology for Quality Management — Enabling Quality Problem Identification and Tracing

    The TOVE Quality Ontology-VB is the formal representation (using First-order Logic) of terms, relationships, attributes, and axioms about quality which are generic beyond any specific quality domain. The assum...

    Global and local measures of the intrinsic Josephson coupling in Tl2Ba2CuO6 as a test of the interlayer tunnelling model

    One leading candidate theory of high-temperature superconductivity in the copper oxide systems is the interlayer tunnelling (ILT) mechanism1. In this model, superconductivity is created by tunnelling of electron ...

    Far- and mid-infrared spectrum of YBa2Cu3O6.0 in high magnetic fields

    The far- and mid-infrared spectrum of antiferromagnetic YBa2Cu3O6.0 was investigated by infrared transmission measurements (→k∥c-axis) in high magnetic fields up to 16.5Tesla at T=1K. A peak at 1436cm −1 which pr...
