Exact diagonalization studies of doped Heisenberg spin rings
Motivated bymagnetization studies of the “telephon number compound” Sr14Cu24O41 we investigate doped Heisenberg spin rings by means of complete numerical diagonalization of a Heisenberg Hamiltonian that depends parametrically on hole positions. A comparison with experimental magnetization data reveals rather accurate information about the screened electrostatic interaction between the charged h...
متن کاملJ 2 quantum Heisenberg antiferromagnet : Improved spin - wave theories versus exact - diagonalization data
We reconsider the results cocerning the extreme-quantum S = 1/2 square-lattice Heisenberg antiferromagnet with frustrating diagonal couplings (J 1 − J 2 model) drawn from a comparison with exact-diagonalization data. A combined approach using also some intrinsic features of the self-consistent spin-wave theory leads to the conclusion that the theory strongly overestimates the stabilizing role o...
متن کاملPersistent spin currents in mesoscopic Heisenberg rings.
We show that at low temperatures T an inhomogeneous radial magnetic field with magnitude B gives rise to a persistent magnetization current around a mesoscopic ferromagnetic Heisenberg ring. Under optimal conditions, this spin current can be as large as gmicro(B)(T/ variant Planck's over 2pi )exp([-2pi(gmicro(B)B/delta)(1/2)], as obtained from leading-order spin-wave theory. Here g is the gyrom...
متن کاملAccelerated convergence in exact-diagonalization studies.
A simple method is proposed and tested for obtaining accelerated convergence of quantum systems on small lattices with N sites. The main idea is to perform exact diagonalizations with some added irrelevant parameter, and use this parameter to accelerate the convergence to the infinitelattice limit. In this paper di8'erent boundary conditions are used to improve the convergence for the Heisenber...
متن کاملThe spin - 1 / 2 J 1 - J 2 Heisenberg antiferromagnet on the square lattice : Exact diagonalization for N = 40 spins
We present numerical exact results for the ground state and the low-lying excitations for the spin-1/2 J 1-J 2 Heisenberg antiferromagnet on finite square lattices of up to N = 40 sites. Using finite-size extrapolation we determine the ground-state energy, the magnetic order parameters, the spin gap, the uniform susceptibility, as well as the spin-wave velocity and the spin stiffness as functio...
