Kondo effect of magnetic impurities on nanotubes
P. P. Baruselli, A. Smogunov, M. Fabrizio +1
The effect of magnetic impurities on the ballistic conductance of nanocontacts is, as suggested in recent work, amenable to ab initio study \cite{naturemat}. Our method proceeds vi…
Critical properties of the double-frequency sine-Gordon model with applications
M. Fabrizio, A. O. Gogolin, A. A. Nersesyan
We study the properties of the double-frequency sine--Gordon model in the vicinity of the Ising quantum phase transition displayed by this model. Using a mapping onto a generalised…
Theory of the Metal-Paramagnetic Mott-Jahn-Teller Insulator Transition in A_4C_{60}
M. Capone, M. Fabrizio, P. Giannozzi +1
We study the unconventional insulating state in A_4C_{60} with a variety of approaches, including density functional calculations and dynamical mean-field theory. While the former…
Phase diagram of doped spin-Peierls systems
M. Fabrizio, R. Mélin, J. Souletie
The phase diagram of a model describing doped CuGeO is derived. The model emphasizes the role of local moments released by the impurities and randomly distributed inside the ga…
Statistical properties of localisation--delocalisation transition in one dimension
M. Steiner, Yang Chen, M. Fabrizio +1
We study a one-dimensional model of disordered electrons (also relevant for random spin chains), which exhibits a delocalisation transition at half-filling. Exact probability distr…
Random Mass Dirac Fermions in Doped Spin-Peierls and Spin-Ladder systems: One-Particle Properties and Boundary Effects
M. Steiner, M. Fabrizio, Alexander O. Gogolin
Quasi-one-dimensional spin-Peierls and spin-ladder systems are characterized by a gap in the spin-excitation spectrum, which can be modeled at low energies by that of Dirac fermion…
