非阿贝尔纯规范理论的含时变分方法
Time-Dependent Variational Approach to the Non-Abelian Pure Gauge Theory
摘要：
在高斯波泛函近似下，用含时变分方法研究了纯Yang-Mills规范理论，特别是色SU（3）规范理论.量子规范场的运动方程用Liouville-von Neumann形式表示。应用这种变分方法，以获得的传输系数，如剪切粘度，为纯胶子物质，通过使用线性响应理论。因此，从量子胶子的剪切粘度的贡献是零的最低阶的耦合g的量子胶子物质。
英文摘要：
The time-dependent variational approach to the pure Yang-Mills gauge theory, especially a color su(3) gauge theory, is formulated in the functional Schroedinger picture with a Gaussian wave functional approximation. The equations of motion for the quantum gauge fields are formulated in the Liouville-von Neumann form. This variational approach is applied in order to derive the transport coefficients, such as the shear viscosity, for the pure gluonic matter by using the linear response theory. As a result, the contribution to the shear viscosity from the quantum gluons is zero up to the lowest order of the coupling g in the quantum gluonic matter.
