Finite-size corrections for the XXX antiferromagnet

L.V. Avdeev, B -D Dorfel

Published Jan 11, 1986• 56 citations

Abstract

The authors present a method of calculating finite-size corrections for the isotropic (XXX) Heisenberg chain in the antiferromagnetic case. The leading corrections to the energy and the root density of the ground state are compared with the numerical data up to N=256 sites in the chain.

Finite-size corrections for spin-S Heisenberg chains and conformal properties

B -D Dorfel

The author compares recent results on finite-size corrections for the isotropic (XXX) Heisenberg chain (and its integrable generalisations) with former numerical and analytic calculations. For the ground state and its lowest excitations, leading and non-leading terms are considered. The analysis confirms the predictions of conformal invariance and sheds some new light on the fine structure of finite-size corrections.

Finite-size corrections in theXYZHeisenberg chain

H. O. Mártin, Hector J. de Vega

We compute the large but finite-size corrections to the XYZ spin-(1/2) Heisenberg chain using a method recently proposed by de Vega and Woynarovich. We derive in closed form the corrections to the ground-state energy and the function \ensuremath{\sigma}(\ensuremath{\lambda}) (finite-size analog to the root density). Different asymptotic regimes are found when the number of sites goes to infinity depending on the two parameters of the Hamiltonian.

Finite-size corrections and numerical calculations for long spin 1/2 Heisenberg chains in the critical region

Ferenc Woynarovich, Hans-Peter Eckle

Leading and next-to-leading-order finite-size corrections to the ground and first excited states are calculated for the spin-1/2 anisotropic Heisenberg model in the critical region. The analytic results are compared to numerical data obtained for chains up to a length of N=1024. It is found that, near the isotropic point, the asymptotic region where the results obtained for N to infinity are applicable sets in at very large N values, and for obtaining good accuracy in fitting the numerical data one has to take into account several correction terms, even at large (N>100) chain lengths.

Calculation of finite-size corrections for the antiferromagnetic Heisenberg chain

B -D Dorfel, St Meißner

The finite-size corrections for the anisotropic Heisenberg model in the gap region are calculated using an exact integral representation based on the Bethe ansatz equations (BAE). The energy corrections are determined by saddle-point approximations for states without complex roots. The case of symmetric states is discussed in greater detail.

Finite-size scaling for the spin-Heisenberg antiferromagnetic chain

Victor Barzykin, Ian K. Affleck

Corrections to the asymptotic correlation function in a Heisenberg spin- antiferromagnetic spin chain are known to vanish slowly (logarithmically) as a function of the distance r or the chain size L . This leads to significant differences with numerical results. We calculate the sub-leading logarithmic corrections to the finite-size correlation function, using renormalization group improved perturbation theory, and compare the result with numerical data.

Numerical test of finite-size corrections for the anisotropic Heisenberg antiferromagnet chain

Djalma Medeiros, G. G. Cabrera

A leading exponential dependence of the mass gap with size has been numerically tested in the whole axial-anisotropy region for the spin-1/2 XXZ antiferromagnetic chain. Exact results for finite chains are obtained via a modified Lanczos method due to Paige, allowing calculations up to N=28 spins. Our results show that the ground state is doubly degenerate and displays long-range order throughout the whole anisotropic regime.
