Emptiness formation probability of the integrable higher-spin XXX and XXZ spin chains through the fusion method
For the integrable higher-spin XXX and XXZ spin chains we show an explicit formula for the multiple-integral representations of the emptiness formation probability (EFP) in the massless ground-state at zero temperature. We first derive it for the inhomogeneous spin-s XXZ chain, and then for the homogeneous chain, sending the spin-s inhomogeneous parameters to zero. We assume 2s-strings for the ...
متن کاملIntegrability of quantum chains: theory and applications to the spin-1/2 XXZ chain
In this contribution we review the theory of integrability of quantum systems in one spatial dimension. We introduce the basic concepts such as the Yang-Baxter equation, commuting currents, and the algebraic Bethe ansatz. Quite extensively we present the treatment of integrable quantum systems at finite temperature on the basis of a lattice path integral formulation and a suitable transfer matr...
متن کاملIntegral representations for correlation functions of the XXZ chain at finite temperature
We derive a novel multiple integral representation for a generating function of the σz-σz correlation functions of the spin-1 2 XXZ chain at finite temperature and finite, longitudinal magnetic field. Our work combines algebraic Bethe ansatz techniques for the calculation of matrix elements with the quantum transfer matrix approach to thermodynamics. PACS: 05.30.-d, 75.10.Pq †e-mail: goehmann@p...
متن کاملDynamical correlation functions of the XXZ model at finite temperature
Combining a lattice path integral formulation for thermodynamics with the solution of the quantum inverse scattering problem for local spin operators, we derive a multiple integral representation for the time-dependent longitudinal correlation function of the spin-1/2 Heisenberg XXZ chain at finite temperature and in an external magnetic field. Our formula reproduces the previous results in the...
متن کاملPath Integral Representation for Interface States of the Anisotropic Heisenberg Model
We develop a geometric representation for the ground state of the spin-1/2 quantum XXZ ferromagnetic chain in terms of suitably weighted random walks in a two-dimensional lattice. The path integral model so obtained admits a genuine classical statistical mechanics interpretation with a translation invariant Hamiltonian. This new representation is used to study the interface ground states of the...
