Droplet states in the XXZ Heisenberg chain
 Communications in Mathematical Physics
, 2001
"... Abstract: We consider the ground states of the ferromagnetic XXZ chain with spin up boundary conditions in sectors with a fixed number of down spins. This forces the existence of a droplet of down spins in the system. We find the exact energy and the states that describe these droplets in the limit ..."

The Thermodynamics of the XXZ Heisenberg Chain with Impurities
, 1999
"... In this paper, we discuss the effect of the arbitrary spin impurities to the spin1/2 and spin1 XXZ model. The effect of ground state, the free energy, the magnetic susceptibility, the specific heat and the Kondo temperature are given by using the thermodynamic Bethe ansatz equation. ..."

Expansions for droplet states in the ferromagnetic XXZ Heisenberg chain
"... We consider the highly anisotropic ferromagnetic spin 1/2 Heisenberg chain with periodic boundary conditions. In each sector of constant total z component of the spin, we develop convergent expansions for the lowest band of eigenvalues and eigenfunctions. These eigenstates describe droplet states in ..."

LPENSLTH03/09 On the thermodynamic limit of form factors in the massless XXZ Heisenberg chain
, 903
"... We consider the problem of computing form factors of the massless XXZ Heisenberg spin1/2 chain in a magnetic field in the (thermodynamic) limit where the size M of the chain becomes large. For that purpose, we take the particular example of the matrix element of the operator σ z between the ground ..."

"... We calculate certain string correlation functions, originally introduced as order parameters in integer spin chains, for the spin1/2 XXZ Heisenberg chain at zero temperature and in the thermodynamic limit. For small distances, we obtain exact results from Bethe Ansatz and exact diagonalization, whe ..."
