手性刘维尔引力

Chiral Liouville Gravity

Geoffrey Compère, Wei Song, Andrew Strominger

摘要:

经典的二维刘维尔引力通常是在具有剩余的左、右Virasoro对称代数的共形规范中考虑的。我们考虑一个交替的手征规范,它有一个剩余的右Virasoro卡茨-穆迪代数,没有左维拉索罗代数。Kac-Moody零模是向左移动的能量。导出了约束哈密顿理论的狄拉克括号,并证明了剩余对称性是由守恒手征流的积分产生的。计算了中心荷和Kac-Moody能级。讨论了相应的量子理论存在的可能性。

英文摘要:

Classical two-dimensional Liouville gravity is often considered in conformal gauge which has a residual left and right Virasoro symmetry algebra. We consider an alternate, chiral, gauge which has a residual right Virasoro Kac-Moody algebra, and no left Virasoro algebra. The Kac-Moody zero mode is the left-moving energy. Dirac brackets of the constrained Hamiltonian theory are derived, and the residual symmetries are shown to be generated by integrals of the conserved chiral currents. The central charge and Kac-Moody level are computed. The possible existence of a corresponding quantum theory is discussed.
