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...
متن کاملEmergent 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...
متن کاملPhase diagram of the Holstein-Hubbard two-leg ladder using a functional renormalization-group method
Using a functional renormalization-group method, we obtain the phase diagram of the two-leg ladder system within the Holstein-Hubbard model, which includes both electron-electron and electron-phonon interactions. Our renormalization-group technique allows us to analyze the problem for both weak and strong electronphonon couplings. We show that, in contrast to results from conventional weak-coup...
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...
