Ground-State Phase Diagram of Frustrated Anisotropic Quantum Spin Chains

The low-energy properties of one-dimensional quantum spin systems with frustrating interactions have been studied extensively for many years. This is mainly because they exhibit a variety of ground-state phases accompanied with various types of spontaneous symmetry breaking, e.g., the dimer phase with the translational symmetry breaking. More recently novel phases have been found in the ground ...

Phase diagram of the two-leg Kondo ladder

The phase diagram of the two-leg Kondo ladder is investigated using computational techniques. Ferromagnetism is present, but only at small conduction electron densities and robust Kondo coupling J. For densities n*0.4 and any Kondo coupling, a paramagnetic phase is found. We also observed spin dimerization at densities n=1/4 and n=1/2. The spin-structure factor at small J peaks at qW = s2n ,0dp...

Magnetic 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...

Emergent Ising degrees of freedom in frustrated two-leg ladder

Based on exact diagonalization data for finite quantum Heisenberg antiferromagnets on two frustrated lattices two-leg ladder and bilayer and analytical arguments we map low-energy degrees of freedom of the spin models in a magnetic field on classical lattice-gas models. Further we use transfer-matrix calculations and classical Monte Carlo simulations to give a quantitative description of low-te...
