Author(s): Sébastien Dusuel, Kai Phillip Schmidt, and Julien Vidal<br/>We analyze the effect of local spin operators in the Kitaev model on the honeycomb lattice. We show, in perturbation around the isolated-dimer limit, that they create Abelian anyons together with fermionic excitations which are likely to play a role in experiments. We derive the explicit form of the...<br/>[Phys. Rev.

Author(s): C. W. Groth, J. Tworzydło, and C. W. Beenakker<br/>By solving a master equation in the Sierpiński lattice and in a planar random-resistor network, we determine the scaling with size L of the shot noise power P due to elastic scattering in a fractal conductor. We find a power-law scaling P∝L^{d_{f} -2-α} , with an exponent depending on the fracta...<br/>[Phys. Rev. Lett. 100, 176804] Published Wed Apr 30, 2008C. W. Groth, J. Tworzydło, and C. W.
