Loop Groups and QNEC

Lorenzo Panebianco

摘要:

本文研究了环群模型的一些分析性质,证明了对任何紧致、单连通李群$G$,环群$LG$的正能量表示(PER)都可以推广到$H^{3/2}(S^1,G)$的PER.然后,我们明确地计算的伴随作用的$H^{5/2}(S^1,G)$的应力能量张量,我们使用这些结果来证明量子势能条件(QNEC)和贝肯斯坦界的状态通过应用索伯列夫循环的真空。在$G=SU(n)$情形下,我们也给出了上述结果的一个简单证明.最后,我们构造并研究了$-1$中不连续环的共轭所诱导的环群共形网的孤子表示。

英文摘要:

We investigate some analytical properties of loop group models, showing that a Positive Energy Representation (PER) of a loop group $LG$ can be extended to a PER of $H^{3/2}(S^1,G)$ for any compact, simple and simply connected Lie group $G$. We then explicitly compute the adjoint action of $H^{5/2}(S^1,G)$ on the stress energy tensor and we use these results to prove the Quantum Null Energy Condition (QNEC) and the Bekenstein Bound for states obtained by applying a Sobolev loop to the vacuum. We also give a simpler proof of these last results in the case $G=SU(n)$. Finally, we construct and study solitonic representations of the loop group conformal nets induced by the conjugation by a loop with a discontinuity in $-1$.
