Boundary susceptibility in the open XXZ-chain
In the first part we calculate the boundary susceptibility χB in the open XXZ-chain at zero temperature and arbitrary magnetic field h by Bethe ansatz. We present analytical results for the leading terms when |h| ≪ α, where α is a known scale, and a numerical solution for the entire range of fields. In the second part we calculate susceptibility profiles near the boundary at finite temperature ...
متن کاملGeneric boundary scattering in the open XXZ chain
The open XXZ spin chain with a general right boundary and a trivial diagonal left boundary is considered. Within this framework we propose a simple computation of the exact generic boundary S-matrix (with diagonal and non-diagonal entries), starting from the ‘bare’ Bethe ansatz equations. Our results coincide with the ones obtained by Ghoshal and Zamolodchikov, after assuming suitable identific...
متن کاملXXZ chain with a boundary
The XXZ spin chain with a boundary magnetic field h is considered, using the vertex operator approach to diagonalize the Hamiltonian. We find explicit bosonic formulas for the two vacuum vectors with zero particle content. There are three distinct regions when h ≥ 0, in which the structure of the vacuum states is different. Excited states are given by the action of vertex operators on the vacuu...
متن کاملInstability of interfaces in the antiferromagnetic XXZ chain at zero temperature
For the antiferromagnetic, highly anisotropic XZ and XXZ quantum spin chains, we impose periodic boundary conditions on chains with an odd number of sites to force an interface (or kink) into the chain. We prove that the energy of the interface depends on the momentum of the state. This shows that at zero temperature the interface in such chains is not stable. This is in contrast to the ferroma...
متن کاملSolving the open XXZ spin chain with nondiagonal boundary terms at roots of unity
We consider the open XXZ quantum spin chain with nondiagonal boundary terms. For bulk anisotropy value η = iπ p+1 , p = 1 , 2 , . . ., we propose an exact (p+1)-order functional relation for the transfer matrix, which implies Bethe-Ansatz-like equations for the corresponding eigenvalues. The key observation is that the fused spin2 transfer matrix can be expressed in terms of a lower-spin transf...
