Scattering matrix for a general gl(2) spin chain
نویسنده
چکیده
We study the general L0-regular gl(2) spin chain, i.e. a chain where the sites {i, i + L0, i + 2L0, . . . } carry the same arbitrary representation (spin) of gl(2). The basic example of such chain is obtained for L0 = 2, where we recover the alternating spin chain. Firstly, we review different known results about their integrability and their spectrum. Secondly, we give an interpretation in terms of particles and conjecture the scattering matrix between them.

Global conjugate gradient method for solving large general Sylvester matrix equation
In this paper, an iterative method is proposed for solving large general Sylvester matrix equation $AXB+CXD = E$, where $A in R^{ntimes n}$ , $C in R^{ntimes n}$ , $B in R^{stimes s}$ and $D in R^{stimes s}$ are given matrices and $X in R^{stimes s}$ is the unknown matrix. We present a global conjugate gradient (GL-CG) algo- rithm for solving linear system of equations with multiple right-han...
متن کاملNested Bethe ansatz for ‘all’ open spin chains with diagonal boundary conditions
We present in an unified and detailed way the nested Bethe ansatz for open spin chains based on Y(gl(n)), Y(gl(m|n)), Ûq(gl(n)) or Ûq(gl(m|n)) (super)algebras, with arbitrary representations (i.e. ‘spins’) on each site of the chain and diagonal boundary matrices (K+(u),K−(u)). The nested Bethe anstaz applies for a general K−(u), but a particular form of the K+(u) matrix. The construction extend...
متن کاملThermodynamical Limit of General Gl(n ) Spin Chains Ii: Excited States and Energies
We consider the thermodynamical limit of a gl(N) spin chain with arbitrary representation at each site of the chain. We consider excitations (with holes and new strings) above the vacuum and compute their corrections in 1 L to the densities and the energy.
متن کاملOpen Perturbatively Long-Range Integrable gl(N) Spin Chains
We construct the most general perturbatively long-range integrable spin chain with spins transforming in the fundamental representation of gl(N) and open boundary conditions. In addition to the previously determined bulk moduli we find a new set of parameters determining the reflection phase shift. We also consider finite-size contributions and comment on their determination. ar X iv :0 80 5. 3...

Optimal conditions are used in nondynamical formalism to diagonalize the pionproton reaction matrix as much as possible. Invariance laws are imposed to simplify the relationship between observables and bilinear combination of amplitudes. Transverse amplitudes are determined by using measured polarization parameter in xfp elastic scattering at 6.0 GeVIC
