On the second reference state and complete eigenstates of the open XXZ chain
نویسندگان
چکیده
The second reference state of the open XXZ spin chain with non-diagonal boundary terms is studied. The associated Bethe states exactly yield the second set of eigenvalues proposed recently by functional Bethe Ansatz. In the quasi-classical limit, two sets of Bethe states give the complete eigenstates of the associated Gaudin model. PACS: 03.65.Fd; 04.20.Jb; 05.30.-d; 75.10.Jm

Spontaneous Magnetization in the Finite XXZ Spin Chain with Boundaries
The finite XXZ spin chain with boundaries is studied. We derive the transfer matrix from the q-difference equation discovered by Cherednik and construct its eigenstates by the vertex operator approach. We point out that the eigenstates with no magnetic fields have a symmetry called the turning symmetry. Making use of this symmetry we calculate the spontaneous magnetization in the thermodynamic ...
متن کاملLocal conservation laws and the structure of the many-body localized states.
We construct a complete set of local integrals of motion that characterize the many-body localized (MBL) phase. Our approach relies on the assumption that local perturbations act locally on the eigenstates in the MBL phase, which is supported by numerical simulations of the random-field XXZ spin chain. We describe the structure of the eigenstates in the MBL phase and discuss the implications of...
متن کاملSupersymmetry on Jacobstahl lattices
It is shown that the construction of Yang and Fendley (2004 J. Phys. A: Math. Gen. 37 8937) to obtain supersymmetric systems, leads not to the open XXZ chain with anisotropy ∆ = −12 but to systems having dimensions given by Jacobstahl sequences. For each system the ground state is unique. The continuum limit of the spectra of the Jacobstahl systems coincide, up to degeneracies, with that of the...
متن کاملA note on the boundary spin s XXZ chain
The open spin s XXZ model with non-diagonal boundaries is considered. Within the algebraic Bethe ansatz framework and in the spirit of earlier works we derive suitable reference states. The derivation of the reference state is the crucial point in this investigation, and it involves the solution of sets of difference equations. For the spin s representation, expressed in terms of difference ope...
متن کاملOn Non-linear Integral Equations and Determinant Formulae of the Open XXZ Spin Chain
We derive for the Bethe-ansatz solvable open XXZ spin chain of arbitrary length a non-linear integral equation describing the ground state. For this case we disclose how to combine the integral representation with the known determinant formula of norms and scalar products.
