On Quasi-Hopf superalgebras
Mark D. Gould, Yao-Zhong Zhang, Phillip S. Isaac
In this work we investigate several important aspects of the structure theory of the recently introduced quasi-Hopf superalgebras (QHSAs), which play a fundamental role in knot the…
Casimir Invariants from Quasi-Hopf (Super)algebras
Mark. D. Gould, Yao-Zhong Zhang, Phillip S. Isaac
We show how to construct, starting from a quasi-Hopf (super)algebra, central elements or Casimir invariants. We show that these central elements are invariant under quasi-Hopf twis…
Integrable Kondo impurities in the one-dimensional supersymmetric U model of strongly correlated electrons
H. -Q. Zhou, X. -Y. Ge, M. D. Gould
Integrable Kondo impurities in the one-dimensional supersymmetric U model of strongly correlated electrons are studied by means of the boundary graded quantum inverse scattering me…
Integrable Kondo impurities in the one-dimensional supersymmetric extended Hubbard model
H. -Q. Zhou, X. -Y. Ge, M. D. Gould
An integrable Kondo problem in the one-dimensional supersymmetric extended Hubbard model is studied by means of the boundary graded quantum inverse scattering method. The boundary…
Quasi-Hopf Superalgebras and Elliptic Quantum Supergroups
Yao-Zhong Zhang, Mark D. Gould
We introduce the quasi-Hopf superalgebras which are graded versions of Drinfeld's quasi-Hopf algebras. We describe the realization of elliptic quantum supergroups as quasi-tr…
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…
Algebraic Bethe ansatz for integrable Kondo impurities in the one-dimensional supersymmetric t-J model
H. -Q. Zhou, M. D. Gould
An integrable Kondo problem in the one-dimensional supersymmetric t-J model is studied by means of the boundary supersymmetric quantum inverse scattering method. The boundary m…
