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 .…
Phantom Energy Accretion onto Black Holes in Cyclic Universe
Cheng-Yi Sun
Black holes pose a serious problem in the cyclic or oscillating cosmology. It is speculated that, in the cyclic universe with phantom turnarounds, black holes will be torn apart by…
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…
current algebra: free field realization and screening currents
Wen-Li Yang, Yao-Zhong Zhang, Xin Liu
The current algebra at general level is investigated. Its free field representation and corresponding energy-momentum tensor are constructed. Seven screening currents…
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…
The Hodge Dual Symmetry of the Green-Schwarz Superstring in
Chuan-Hua Xiong
The hidden symmetry and an infinite set non-local conserved currents of the Green-Schwarz superstring on have been pointed out by Bena et al. In this paper, we s…
