CFT凸性猜想的一个反例
A counterexample to the CFT convexity conjecture
AI总结:
本文针对arXiv:2108.04594提出的CFT中固定荷最小算符维数为荷的凸函数这一猜想,构造了一个经修改的类clockwork弱耦合CFT作为反例,并探讨了模型应用及未被否定的修正版猜想。
摘要:
受弱引力猜想启发,arXiv:2108.04594提出猜想:在任意共形场论(CFT)中,固定荷下的最小算符维数是荷的凸函数。本文构造了该凸性猜想的一个反例,它是一种类clockwork模型,经修改后成为弱耦合CFT。我们还讨论了该模型的进一步潜在应用,以及未被此反例否定的若干修正版猜想。
英文摘要:
Motivated by the weak gravity conjecture, arXiv:2108.04594 conjectured that in any CFT, the minimal operator dimension at fixed charge is a convex function of the charge. In this letter we construct a counterexample to this convexity conjecture, which is a clockwork-like model with some modifications to make it a weakly-coupled CFT. We also discuss further possible applications of this model and some modified versions of the conjecture which are not ruled out by the counterexample.
