Excitation spectrum of a generalised Heisenberg ferromagnetic spin chain with arbitrary spin

Abstract

The m-magnon bound state (or soliton) excitation spectrum of an exactly solvable generalisation of the Heisenberg spin chain with arbitrary S is described. It is in qualitative agreement with predictions based on the classical continuum model. The classical limit of the generalised model is obtained.

The spectrum of the continuous isotropic quantum Heisenberg chain: quantum solitons as magnon bound states

Hans C. Fogedby

The continuous Heisenberg chain is quantised semiclassically. The spectrum consists of unit spin bosons (magnons) and integer spin bosons (solitons) with dispersion laws E=JS(ka) 2 and E n =16JS 3 sin 2 (ka/4S)/n (n=1...) respectively. It is proposed that the n=1 soliton is the magnon and that the spectrum is exact, including all quantum corrections. For S= 1 / 2 the spectrum agrees with results for the discrete chain and it is inferred that the soliton is a multi-magnon bound state.

Excitation spectrum of the ferromagnetic Ising-Heisenberg chain at zero field

T. Schneider, E. Stoll

The excitation spectrum of the ferromagnetic $s=\frac{1}{2}$ Ising-Heisenberg chain as probed by dynamic form factors is studied. Exact results are presented for zero temperature, and the modifications introduced by thermally induced transitions are elucidated by finite-chain calculations. A particularly interesting result is the occurrence of a thermally induced resonance around zero frequency for an Ising-like model. Its origin is traced back to transitions involving magnon bound states. The resonance structure of the dynamic form factors associated with a Heisenberg-like system turns out to be less spectacular, because the contributions of different induced transitions nearly overlap on the frequency scale; so that rather broad resonance structures result. Our findings have an important bearing on related models with $s>\frac{1}{2}$, such as CsNi${\mathrm{F}}_{3}$, and on the soliton aspect of the classically treated systems.

Bound states and correlation functions in the easy-plane Heisenberg ferromagnetic chain

H J Jensen, Hans C. Fogedby

The two-magnon excitation spectrum of the quantum spin-one easy-plane Heisenberg ferromagnetic chain is discussed. The spin-spin correlation functions are calculated within a systematic perturbation theory in terms of the anisotropy, and contributions from the two-magnon bound states are discussed. The results are compared with the predictions for non-interacting spin waves.

The two-magnon bound states spectrum in generalised ferromagnetic chains

Andrey V. Chubukov, D. V. Khveschenko

The two-particle bound states spectrum in generalised quantum 1D ferromagnets is studied in detail. It is shown that the behaviour inherent in integrable models with S>or=1 is realised on a whole surface in a space of Hamiltonian's parameters.

Excitation Spectrum of the Ising-Heisenberg Chain Ferromagnet

T. Schneider, E. Stoll

Results are presented and interpreted for the zero- and finite-temperature excitation spectrum of ferromagnetic Ising-Heisenberg chains, as probed by dynamic form factors. Finite-chain calculations demonstrate the occurrence of a thermally induced resonance centered around zero frequency, and a broadening of the magnon and two-magnon bound-state resonances at low $T$. The occurrence of bound states in the associated transitions demonstrates the failure of finite-order magnon perturbation theory.

Solitons in quantum Heisenberg chain

Marek Cieplak, Łukasz A. Turski

Using the coherent states method combined with the Schwinger coupled boson representation of the spin operators (1965) it is shown that solitons can propagate in the continuum limit of the quantum ferromagnetic Heisenberg chain. These solitons are solutions of a nonlinear Schrodinger equation similar to that discussed by Lakshmanan (1977) for the classical Heisenberg chain. Several characteristics of the soliton, like its momentum, energy, and the number of bosonic excitations involved in the soliton formation, are calculated.
