Spin Chains in an External Magnetic Field. Closure of the Haldane Gap and Effective Field Theories
L. Campos Venuti, E. Ercolessi, G. Morandi +2
We investigate both numerically and analytically the behaviour of a spin-1 antiferromagnetic (AFM) isotropic Heisenberg chain in an external magnetic field. Extensive DMRG studies…
Charge Order Driven spin-Peierls Transition in NaV2O5
Y. Fagot-Revurat, M. Mehring, R. K. Kremer
We conclude from 23Na and 51V NMR measurements in NaxV2O5(x=0.996) a charge ordering transition starting at T=37 K and preceding the lattice distortion and the formation of a spin…
Quantum Monte Carlo simulations of the half-filled two-dimensional Kondo lattice model
F. F. Assaad
The 2D half-filled Kondo lattice model with exchange J and nearest neighbor hopping t is considered. It is shown that this model belongs to a class of Hamiltonians for which zero-t…
Single hole dynamics in the one dimensional t-J model
Michael Brunner, Fakher F. Assaad, Alejandro Muramatsu
We present a new finite-temperature quantum Monte Carlo algorithm to compute imaginary-time Green functions for a single hole in the t-J model on non-frustrated lattices. Spectral…
