Quantum Phase Diagram of an Exactly Solved Mixed Spin Ladder
We investigate the quantum phase diagram of the exactly solved mixed spin-(1 2 , 1) ladder via the thermodynamic Bethe ansatz (TBA). In the absence of a magnetic field the model exhibits three quantum phases associated with su(2), su(4) and su(6) symmetries. In the presence of a strong magnetic field, there is a third and full saturation magnetization plateaux within the strong antiferromagneti...
متن کاملPhase diagram of the non-hermitean asymmetric XXZ spin chain
The low-lying excitations of the asymmetric XXZ spin chain are derived explicitly in the antiferromagnetic regime through the Bethe Ansatz. It is found that a massless and conformal invariant phase with central charge c = 1 is separated from a massive phase by a line on which the low-lying excitations surprisingly scale with the lattice length as ∆E ∼ N 1 2 . The mass gap vanishes with an expon...
متن کاملMagnetic Phase Diagram of Spin-1/2 Two-Leg Ladder with Four-Spin Ring Exchange
We study the spin-1/2 two-leg Heisenberg ladder with four-spin ring exchanges under a magnetic field. We introduce an exact duality transformation which is an extension of the spin-chirality duality developed previously and yields a new self-dual surface in the parameter space. We then determine the magnetic phase diagram using the numerical approaches of the density-matrix renormalization-grou...
متن کاملPhase diagram study of a dimerized spin-S zig-zag ladder.
The phase diagram of a frustrated spin-S zig-zag ladder is studied through different numerical and analytical methods. We show that for arbitrary S, there is a family of Hamiltonians for which a fully-dimerized state is an exact ground state, being the Majumdar-Ghosh point for a particular member of the family. We show that the system presents a transition between a dimerized phase to a Néel-li...
متن کاملMagnetic phase diagram of the dimerized spin S = 1 2 ladder
The ground-state magnetic phase diagram of a spin S = 1/2 two-leg ladder with alternating rung exchange J⊥(n) = J⊥[1 + (−1) nδ] is studied using the analytical and numerical approaches. In the limit where the rung exchange is dominant, we have mapped the model onto the effective quantum sineGordon model with topological term and identified two quantum phase transitions at magnetization equal to...
