چکیده
A bstract We present and solve a soliton equation which we call the non-chiral intermediate Heisenberg ferromagnet (ncIHF) equation. This equation, depends on parameter ? > 0, describes time evolution of two coupled spin densities propagating real line, in limit ? ? it reduces to decoupled half-wave maps (HWM) equations opposite chirality. show that ncIHF is related -type hyperbolic Calogero-Moser (CM) system distinct ways: (i) obtained as particular continuum an Inozemtsev-type chain this CM system, (ii) has multi-soliton solutions by spin-pole ansatz with parameters satisfying motion complexified version system. The integrability shown constructing Lax pair. also propose periodic variant elliptic

Chiral Metal as a Heisenberg Ferromagnet
The two-dimensional surface of an integer quantum hall multilayer is mapped onto a Heisenberg spin chain with ferromagnetic coupling. Using this mapping it is shown nonperturbatively that the surface states constitute a very anisotropic metal in the infinite size limit. For multilayers of finite size, two diffusive mesoscopic regimes are identified and the conductance fluctuations are calculate...
متن کاملQMC simulations of Heisenberg ferromagnet
We use the Quantum Monte Carlo Stochastic Series Expansion (SSE) algorithm to investigate the properties of the one-dimensional Heisenberg ferromagnet. We consider the model for two spin values s = 1 2 and s = 1 and study the dependence of the specific heat, magnetisation, magnetic susceptibility and correlation functions on temperature and magnetic field. Obtained results are compared to those...
متن کاملQuantum Stability for the Heisenberg Ferromagnet
Highly spinning classical strings on R×S are described by the Landau– Lifshitz model or equivalently by the Heisenberg ferromagnet in the thermodynamic limit. The spectrum of this model can be given in terms of spectral curves. However, it is a priori not clear whether any given admissible spectral curve can actually be realised as a solution to the discrete Bethe equations, a property which ca...
متن کاملSpin Waves in the Dilute Heisenberg Ferromagnet
The energy of long wave length spin waves in dilute Heisenberg ferromagnets is calculated. It is shown that spin waves can exist only within an infinite cluster of magnetic spins and that such spin waves are mechanically stable. Heuristic arguments based on dimensionality of the infinite cluster imply that there is no thermal instability of the type discussed by Mermin and Wagner. Thus, the cri...
متن کاملMore on Generalized Heisenberg Ferromagnet Models
We generalize the integrable Heisenberg ferromagnet model according to each Hermitian symmetric spaces and address various new aspects of the generalized model. Using the first order formalism of generalized spins which are defined on the coadjoint orbits of arbitrary groups, we construct a Lagrangian of the generalized model from which we obtain the Hamiltonian structure explicitly in the case...
