On explicit free field realizations of current algebras
Wen-Li Yang, Yao-Zhong Zhang
We construct the explicit free field representations of the current algebras , and for a generic positive integer and an arbitrary level .…
Free field realization of current superalgebra
Wen-Li Yang, Yao-Zhong Zhang, Xin Liu
We construct the free field representation of the affine currents, energy-momentum tensor and screening currents of the first kind of the current superalgebra uniformly…
Multiple reference states and complete spectrum of the Belavin model with open boundaries
Wen-Li Yang, Yao-Zhong Zhang
The multiple reference state structure of the Belavin model with non-diagonal boundary terms is discovered. It is found that there exist reference states, each of them y…
Exact classical solutions of nonlinear sigma models on supermanifolds
Ryu Sasaki, Wen-Li Yang, Yao-Zhong Zhang
We study two-dimensional nonlinear sigma models with target spaces being the complex super Grassmannian manifolds, that is, coset supermanifolds $G(m,p|n,q)\cong U(m|n)/[U(p|q)\oti…
Determinant Representation of Correlation Functions for the Free Fermion Model
Shao-You Zhao, Wen-Li Yang, Yao-Zhong Zhang
With the help of the factorizing -matrix, the scalar products of the free fermion model are represented by determinants. By means of these results, we obtain the…
A note on the non-diagonal K-matrices for the trigonometric vertex model
Wen-Li Yang, Yao-Zhong Zhang
This note presents explicit matrix expressions of a class of recently-discovered non-diagonal K-matrices for the trigonometric vertex model. From these explicit exp…
