The superstring theories have implications in the higher dimensional cosmology. In this research project we have achieved many aspects of black holes in higher dimensional spacetime, evaporation by the Hawking effect. Some of them are purely classical like topology of black hole and the others arequantum information theoretical.Also lower dimensional conformal field theory, which is the basis of string theory, and quantum gravity has been investigated by using simulations

超弦理论在更高维的宇宙学中也有应用。在这个研究项目中，我们已经实现了许多方面的黑洞在高维时空，蒸发的霍金效应。其中有些是纯经典的，如黑洞的拓扑结构，有些是量子信息理论，还对作为弦论基础的低维共形场论和量子引力进行了模拟研究
