Class of Exact Solutions of the SU(3) Skyrme Model
Wang-Chang Su
Recently, Hirayama and Yamashita have presented an ansatz that allows us to construct a class of solutions for the SU(2) Skyrme model. Though these solutions are not solitonic, the…
Conformal Covariantization of Moyal-Lax Operators
Ming-Hsien Tu, Niann-Chern Lee, Yu-Tung Chen
A covariant approach to the conformal property associated with Moyal-Lax operators is given. By identifying the conformal covariance with the second Gelfand-Dickey flow, we covaria…
Semiclassical Quantization of Hopf Solitons
Wang-Chang Su
The gauge equivalent formulation of the Faddeev-Skyrme model is used for the study of the quantum theory. The rotational quantum excitations around the soliton solution of Hopf num…
Faddeev-Skyrme Model and Rational Maps
Wang-Chang Su
The Faddeev-Skyrme model, a modified O(3) nonlinear sigma model in three space dimensions, is known to admit topological solitons that are stabilized by the Hopf charge. The Faddee…
$W_n^{(\ka)}$ algebra associated with the Moyal KdV Hierarchy
Ming-Hsien Tu
We consider the Gelfand-Dickey (GD) structure defined by the Moyal -product with parameter $\ka$, which not only defines the bi-Hamiltonian structure for the generalized Moy…
Self-consistent renormalization group flow
Sen-Ben Liao, Chi-Yong Lin, Michael Strickland
A self-consistent renormalization group flow equation for the scalar lambda phi^4 theory is analyzed and compared with the local potential approximation. The two prescriptions coin…
