非临界Liouville弦模型中单圈自由能的计算

The Calculation of One Loop Free Energy in Non-Critical Liouville String Model

该文采用路径积分方法计算了非临界Liouville弦模型中单圈自由能,结果表明D=27时的临界温度与共形物质场的中心荷有关,并获得了自由能的渐近表达式。

In this paper, the one loop free energy in non-critical Liouville string model is calculated by using path integral method. The result shows that critical temperature depends on the central charge of eonformal matter field at D = 27, and the asymptotic expression of free energy is also obtained.
