We give the center of the elliptic quantum group in general case. Based on the Dynamic Yang-Baxter Relation and the fusion method, we prove that the center commute with all generators of the elliptic quantum group. Then for a kind of assumed form of these generators, we find that the coefficients of these generators form a new type closed algebra. We also… (More)
Boundary operators and boundary states in SU (2)-invariant Thirring model are considered from the point of view of bosonization and oscillator realizations of bulk and boundary Zamolodchikov-Faddeev algebras.
A general method is proposed for constructing the Bethe ansatz equations of integrable models without U(1) symmetry. As an example, the exact spectrum of the XXZ spin ring with a Möbius-like topological boundary condition is derived by constructing a modified T-Q relation based on the functional connection between the eigenvalues of the transfer matrix and… (More)
The off-diagonal Bethe Ansatz method  is used to revisit the periodic XXX Heisenberg spin-1 2 chain. It is found that the spectrum of the transfer matrix can be characterized by an inhomogeneous T-Q relation, a natural but nontrivial extension of Baxter's T-Q relation .
In this paper, we give the general forms of the minimal L matrix (the elements of the L-matrix are c numbers) associated with the Boltzmann weights of the A 1 n−1 interaction-round-a-face (IRF) model and the minimal representation of the A n−1 series elliptic quantum group given by Felder and Varchenko. The explicit dependence of elements of L-matrices on… (More)
In this paper, we show the integrability of spin-1/2 XXZ Heisenberg chain with two arbitrary spin boundary Impurities. By using the fusion method, we generalize it to the spin-1 XXZ chain. Then the eigenvalues of Hamiltonians of these models are obtained by the means of Bethe ansatz method. 1. Introduction Recently, more and more papers have focused on the… (More)
In this paper, we discuss the effect of the arbitrary spin impurities to the spin-1/2 and spin-1 XXZ model. The effect of ground state, the free energy, the magnetic susceptibility, the specific heat and the Kondo temperature are given by using the thermodynamic Bethe ansatz equation.
Binding of Zn(2+) to the coordinating supramolecular vesicle based on an aggregation induced emission amphiphile TPE-BPA immediately triggers the formation of charged vesicles. This induces vesicle fission and fluorescence reduction, suggesting a looser molecular packing in the charged vesicle membrane. Since cancer cells are highly charged, this indicates… (More)
