摘要:

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.

关键词: 非临界Liouville 弦, 温度, 单圈自由能

Abstract:

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 conformal matter field at D=27, and  the asymptotic expression of free energy is also obtained.

Key words: Non-Critical Liouville string, Temperature, One loop free energy.
