Magnetic Phase Transition at 88 K in Na0.5CoO2 revealed by 23Na-NMR investigations
B. Pedrini, J. L. Gavilano, S. Weyeneth +6
Na0.5CoO2 exhibits a metal-insulator transition at 53 K upon cooling. The nature of another transition at 88 K has not been fully clarified yet. We report the results of measuremen…
NMR and dc-susceptibility studies of NaVGe2O6
B. Pedrini, J. L. Gavilano, D. Rau +4
We report the results of measurements of the dc magnetic susceptibility chi(T) and of the 23Na nuclear magnetic resonance (NMR) response of NaVGe2O6, a material in which the V ions…
Axions, Quantum Mechanical Pumping, and Primeval Magnetic Fields
J. Froehlich, B. Pedrini
We discuss the ordinary quantum Hall effect and a higher-dimensional cousin. We consider the dimensional reduction of these effects to 1+1 and 3+1 space-time dimensions, respective…
Universality in Quantum Hall Systems: Coset Construction of Incompressible States
J. Froehlich, B. Pedrini, C. Schweigert +1
Incompressible Quantum Hall fluids (QHF's) can be described in the scaling limit by three-dimensional topological field theories. Thanks to the correspondence between three-dimensi…
