Spin gap and Luttinger liquid description of the NMR relaxation in carbon nanotubes
Balázs Dóra, Miklós Gulácsi, Ferenc Simon +1
Recent NMR experiments by Singer et al. [Singer et al. Phys. Rev. Lett. 95, 236403 (2005).] showed a deviation from Fermi-liquid behavior in carbon nanotubes with an energy gap evi…
Charge Order in the Falicov-Kimball Model
P. M. R. Brydon, M. Gulacsi
We examine the spinless one-dimensional Falicov-Kimball model (FKM) below half-filling, addressing both the binary alloy and valence transition interpretations of the model. Using…
Bosonization solution of the Falicov-Kimball model
P. M. R. Brydon, M. Gulacsi
We use a novel approach to analyze the one dimensional spinless Falicov-Kimball model. We derive a simple effective model for the occupation of the localized orbitals which clearly…
Competing Orderings in an Extended Falicov-Kimball Model
P. M. R. Brydon, Jian-Xin Zhu, M. Gulacsi +1
We present a Hartree-Fock study of the Falicov-Kimball model extended by both on-site and non-local hybridization. We examine the interplay between excitonic effects and the charge…
Spin and lattice effects in the Kondo lattice model
M. Gulacsi, A. Bussmann-Holder, A. R. Bishop
The magnetic properties of a system of coexisting localized spins and conduction electrons are investigated within an extended version of the one dimensional Kondo lattice model in…
Exact Unitary Transformation of the One-Dimensional Periodic Anderson Model
Raymond Chan, Miklos Gulacsi
An effective hamiltonian is derived exactly for the one-dimensional periodic Anderson model via a canonical transformation. The canonical transformation has been calculated up to i…
