The Links-Gould Invariant of Links
David De Wit, Louis H Kauffman, Jon R Links
We introduce and study in detail an invariant of (1,1) tangles. This invariant, derived from a family of four dimensional representations of the quantum superalgebra U_q[gl(2|1)],…
New integrable model of correlated electrons with off-diagonal long-range order from symmetry
Angela Foerster, Jon Links, Itzhak Roditi
We present a new integrable model for correlated electrons which is based on a symmetry. By using an -pairing realization we construct eigenstates of the Hamiltonian wit…
Graded reflection equation algebras and integrable Kondo impurities in the one-dimensional t-J model
H. -Q. Zhou, X. -Y. Ge, J. Links +1
Integrable Kondo impurities in two cases of the one-dimensional model are studied by means of the boundary -graded quantum inverse scattering method. The boundary…
Bethe ansatz solution of a closed spin 1 XXZ Heisenberg chain with quantum algebra symmetry
Jon Links, Angela Foerster, Michael Karowski
A quantum algebra invariant integrable closed spin 1 chain is introduced and analysed in detail. The Bethe ansatz equations as well as the energy eigenvalues of the model are obtai…
Integrability of a t-J model with impurities
Jon Links, Angela Foerster
A t-J model for correlated electrons with impurities is proposed. The impurities are introduced in such a way that integrability of the model in one dimension is not violated. The…
Integrable multiparametric quantum spin chains
Angela Foerster, Jon Links, Itzhak Roditi
Using Reshetikhin's construction for multiparametric quantum algebras we obtain the associated multiparametric quantum spin chains. We show that under certain restrictions these mo…
