非相对论性弦理论是一个具有非相对论性弦谱的幺正紫外有限量子引力理论。世界片理论的顶点算符决定了非相对论性弦理论的时空几何,即弦牛顿-嘉当几何。我们计算的Weyl异常的非相对论弦世界片西格玛模型描述的字符串传播的字符串牛顿-Cartan几何,Kalb-Ramond和Escherton背景。我们导出了运动方程,这些方程决定了非相对论性弦理论可以用量子力学一致地定义的背景。我们从世界片理论的共形异常研究中发现的运动方程对于非相对论性弦理论就像(超)引力运动方程对于相对论性弦理论一样。
Nonrelativistic string theory is a unitary, ultraviolet finite quantum gravity theory with a nonrelativistic string spectrum. The vertex operators of the worldsheet theory determine the spacetime geometry of nonrelativistic string theory, known as the string Newton-Cartan geometry. We compute the Weyl anomaly of the nonrelativistic string worldsheet sigma model describing strings propagating in a string Newton-Cartan geometry, Kalb-Ramond and dilaton background. We derive the equations of motion that dictate the backgrounds on which nonrelativistic string theory can be consistently defined quantum mechanically. The equations of motion we find from our study of the conformal anomaly of the worldsheet theory are to nonrelativistic string theory what the (super)gravity equations of motion are to relativistic string theory.
