Explicit field realizations of W algebras
Shao-Wen Wei, Yu-Xiao Liu, Li-Jie Zhang +1
The fact that certain non-linear algebras can be linearized by the inclusion of a spin-1 current can provide a simple way to realize algebras from linear $W_{1,…
Physical States and BRST Operators for Higher-spin Strings
Yu-Xiao Liu, Shao-Wen Wei, Li-Jie Zhang +1
In this paper, we mainly investigate the system, in which the matter and the Liouville subsystems generate and algebras r…
Spinor Field Realizations of the half-integer Strings
Shao-Wen Wei, Yu-Xiao Liu, Li-Jie Zhang +1
The grading Becchi-Rouet-Stora-Tyutin (BRST) method gives a way to construct the integer strings, where the BRST charge is written as . Using this method, we…
Fermionic Zero Modes in Gauge and Gravity Backgrounds on a Sphere
Yu-Xiao Liu, Li-Jie Zhang, Yi-Shi Duan
In this letter we study fermionic zero modes in gauge and gravity backgrounds taking a two dimensional compact manifold as extra dimensions. The result is that there exist ma…
Spinor field realizations of the non-critical string based on the linear algebra
Li-Jie Zhang, Yu-Xiao Liu
In this paper, we investigate the spinor field realizations of the algebra, making use of the fact that the algebra can be linearized through the addition of a…
Corrections to the Nonrelativistic Ground Energy of a Helium Atom
Yi-Shi Duan, Yu-Xiao Liu, Li-Jie Zhang
Considering the nuclear motion, the authors give out the nonrelativistic ground energy of a helium atom by using a simple but effective variational wave function with a flexible pa…
