NMR Evidence for Gapped Spin Excitations in Metallic Carbon Nanotubes
P. M. Singer, P. Wzietek, H. Alloul +2
We report on the spin dynamics of 13C isotope enriched inner-walls in double-wall carbon nanotubes (DWCNT) using 13C nuclear magnetic resonance (NMR). Contrary to expectations, we…

1/T_1 nuclear relaxation time of κ-(BEDT-TTF)_ 2 Cu [N(CN)_2] Cl : effects of magnetic frustration
I. J. Hamad, A. E. Trumper, P. Wzietek +2
We study the role played by the magnetic frustration in the antiferromagnetic phase of the organic salt κ-(BEDT-TTF)_ 2 Cu [N(CN)_2] Cl. Using the spatially anisotropic triangular…

Universality and Critical Behavior at the Mott transition
P. Limelette, A. Georges, D. Jerome +3
We report conductivity measurements of Cr-doped V2O3 using a variable pressure technique. The critical behavior of the conductivity near the Mott-insulator to metal critical endpoi…
