Rainar Nitzsche (2012): Spinnen kennen lernen. Eklig [ekelig], giftig oder zum Kuscheln? Wie Spinnen wirklich sind.

Um es gleich am Anfang zu sagen: Das Buch von Rainar Nitzsche ist kein Fachbuch für Arachnologen, sondern ein Buch, das aus Rainars Erfahrungen entstanden ist Kindern und Jugendlichen das Thema Spinnen näher zu bringen, um Interesse an Ihnen zu wecken oder gar Vorurteile und Ängste ab zu bauen

Flux tubes, visons, and vortices in spin-charge separated superconductors

The idea of spin-charge separation in cuprate superconductors has been recently energized by Senthil and Fisher who formulated a Z_2 gauge theory and, within its context, proposed a ``vison detection'' experiment as a test for topological order in a sample with multiply connected geometry. Here we show that the same experiment can be performed to test for the spin-charge separation in U(1) [but not in SU(2)] theory and argue that vortex core spectroscopy can in fact distinguish between the different symmetries of the fictitious gauge field.Comment: 3 pages, 1 ps figure.

Bound states and extended states around a single vortex in the d-wave superconductors

Making use of the Bogoliubov-de Gennes equation for the d-wave superconductors, we investigate the quasi-particle spectrum around a single vortex. Taking $p_F\xi=10$, we found that there are bound states which are localized around the vortex core, and extended states which are rather uniform, for $|E|<\Delta$ where $E$ is the quasi-particle energy and $\Delta$ is the asymptotic value of the order parameter for away from the vortex.Comment: 4 pages, 6 figure

Quasiparticle spectra in the vicinity of a d-wave vortex

We discuss the evolution of the local quasiparticle spectral density and the related tunneling conductance measurable by the scanning tunneling microscope, as a function of distance r and angle \theta from the vortex core in a d_{x^2-y^2} superconductor. We consider the effects of electronic disorder and of a strongly anisotropic tunneling matrix element, and show that in real materials they will likely obscure the ~1/r asymptotic tail in the zero-bias tunneling conductance expected from the straightforward semiclassical analysis. We also give a prediction for the tunneling conductance anisotropy around the vortex core and establish a connection to the structure of the tunneling matrix element.Comment: 9 pages REVTeX + 5 PostScript figures.
