费米子弦与量子引力态的联系--圈空间方法

Connection between Fermionic Strings and Quantum Gravity States -- A loop space approach

Luiz C. L. Botelho

摘要:

基于Dirac/Klein-gordon行列式的圈空间表示,我们证明了在Ashtekar-Sen联络正则形式下,在临界点上定义在时空基流形上的某些合适的费米弦伊辛模型是引力场的形式量子态.这些结果补充了我们以前在圈空间中对这一问题的研究(爱因斯坦量子引力的随机表面表示,物理评论D52,6941(1995))

英文摘要:

We present physical arguments based on loop space representations for Dirac/Klein gordon determinants that some suitable Fermionic String Ising models at the critical point and defined on the space-time base manifold are formal quantum states of the gravitational field when quantized in the Ashtekar-Sen connection canonical formalism .These results complements our previous Loop Space studies on the subject (Random surface representation for Einstein quantum gravity, Phys.Rev.D52,6941 (1995))
