The Magnetization of Cu_2(C_5H_{12}N_2)_2Cl_4 : A Heisenberg Spin Ladder System
C. A. Hayward, D. Poilblanc, L. P. Lévy
We study the magnetization of a Heisenberg spin ladder using exact diagonalization techniques, finding three distinct magnetic phases. We consider the results in relation to the ex…
Optical Conductivity of a t--J Ladder
C. A. Hayward, D. Poilblanc, D. J. Scalapino
The optical conductivity of a doped two-leg t--J ladder is calculated for an electric field polarized parallel to the legs of the ladder. The conductivity has a Drude weight…
Luttinger liquid behaviour and superconducting correlations in t-J ladders
C. A. Hayward, D. Poilblanc
The low energy behaviour of the isotropic t--J ladder system is investigated using exact diagonalization techniques, specifically finding the Drude weight, the charge velocity and…
Evidence for a superfluid density in t--J ladders
C. A. Hayward, D. Poilblanc, R. M. Noack +2
Applying three independent techniques, we give numerical evidence for a finite superfluid density in isotropic hole-doped t--J ladders: We show the existence of anomalous flux quan…
