Applicability of the Friedberg-Lee-Zhao method
Gong-Bo Zhao, Yi-Bing Ding, Xue-Qian Li +2
Friedberg, Lee and Zhao proposed a method for effectively evaluating the eigenenergies and eigen wavefunctions of quantum systems. In this work, we study several special cases to i…
SO(5) structure of p-wave superconductivity for spin-dipole interaction model
Hong-Biao Zhang, Mo-Lin Ge, Kang Xue
A closed SO(5) algebraic structure in the the mean-field form of the Hamiltonian the pure p-wave superconductivity is found that can help to diagonalized by making use of the Bogol…
Local U(1) symmetry in Y(so(5)) associated with Massless Thirring Model and its Bethe Ansatz
Hong-Biao Zhang, Mo-Lin Ge, Kang Xue
The Massless Thirring model associated with SO(5) is solved in terms of the local U(1) symmetry. The local U(1) symmetry is related to q-deformation of four-component field operato…
Y(so(5)) symmtry of the nonlinear Schrdinger model with four-cmponents
Hong-Biao Zhang, Mo-Lin Ge, Kang Xue
The quantum nonlinear Schrdinger(NLS) model with four-component fermions exhibits a symmetry when considered on an infintite interval. The constructed generato…
Asymmetry of Strange Sea in Nucleons
Xue-Qian Li, Xiao-Bing Zhang, Bo-Qiang Ma
Based on the finite-temperature field theory, we evaluate the medium effects in nucleon which can induce an asymmetry between quarks and antiquarks of the strange sea. The short-di…
Molecular States and 1^-+ Exotic Mesons
Rui Zhang, Yi-Bing Ding, Xue-Qian Li +1
This work investigates whether the observed 1^-+ exotic mesons are molecular states. We first use a potential model to calculate the spectra and lifetimes of the f_0(980) and a_0(9…
