    : Fractionalization-the breaking up of an apparently indivisible microscopic degree of freedom-is one of the most counterintuitive phenomena in many-body physics. Here we study its most fundamental manifestation in spin ice, the only known fractionalized magnetic compou...

    We solve a long standing problem with relativistic calculations done with the widely used Multi-Configuration Dirac-Fock Method (MCDF). We show, using Relativistic Many-Body Perturbation Theory (RMBPT), how even for relatively high-$Z$, relaxation or correlation causes ...

    We use microwave excitation to elucidate the dynamics of long superconductor / normal metal / superconductor Josephson junctions. By varying the excitation frequency in the range 10 MHz - 40 GHz, we observe that the critical and retrapping currents, deduced from the dc ...

    : Recent studies show that two low-energy van Hove singularities (VHSs) seen as two pronounced peaks in the density of states could be induced in a twisted graphene bilayer. Here, we report angle-dependent VHSs of a slightly twisted graphene bilayer studied by scanning ...

    The impacts of climate and environmental changes on migration have gained increasing attention in recent years. Yet the role and significance of the climate as an influencing factor for migratory processes is still poorly understood. Case studies are required which cons...

  • Die Elbe ist mit einer Länge von ca. 1.100 km und einem Gesamteinzugsgebiet von knapp 150.000 km2 einer der größten Flüsse Mitteleuropas. Bis heute wurden etwa 80 % der Auen des Flusses eingedeicht. Dennoch blieben trotz Ausbau als Wasserstraße weite Bereiche als naturn...

    "Nicht nur die Vernunft von Jahrtausenden – auch ihr Wahnsinn bricht an uns aus. Gefährlich ist es, Erbe zu sein. Noch kämpfen wir Schritt um Schritt mit dem Riesen Zufall, und über der ganzen Menschheit waltete bisher noch der Unsinn, der Ohne-Sinn, warnt Nietzsches Pr...
