Magnetic phase diagram of a frustrated ferrimagnetic ladder: Relation to the one-dimensional boson Hubbard model
N. B. Ivanov, J. Richter
Abstract
We study the magnetic phase diagram of two coupled mixed-spin (1,1/2) Heisenberg chains as a function of the frustration parameter related to diagonal exchange couplings. The analysis is performed by using spin-wave series and exact numerical diagonalization techniques. The obtained phase diagram--containing the Luttinger liquid phase, the plateau phase with a magnetization per rung M=1/2, and the fully polarized phase--is closely related to the generic (J/U,μ/U) phase diagram of the one-dimensional boson Hubbard model.
