有限N黑洞上同调研究
近日,韩国首尔大学的Jaehyeok Choi与韩国高等研究院的Sunjin Choi等人合作,对有限N黑洞上同调进行了研究。相关研究成果已于2024年12月4日在国际知名学术期刊《高能物理杂志》上发表。
该研究团队研究了具有SU(3)和SU(4)规范群的N=4杨-米尔斯理论中BPS算符的新上同调,以更深入地理解黑洞微态。首先,研究人员研究了这些黑洞算符的指数,并确定了它们明显的阈值能级。
对于SU(3)的情况,研究人员发现了许多状态塔和部分无毛行为,并明确构建了SU(3)理论中的阈值上同调。
在本文中,研究人员始终研究了一个对应于BMN矩阵理论的场论子分区。他们还论证了在大N情况下,BMN分区展现出类似黑洞的熵增长特性。

Abstract: We study new cohomologies for the BPS operators of the N = 4 Yang-Mills theory with SU(3) and SU(4) gauge groups, to better understand the black hole microstates. We first study the index of these black hole operators and identify their apparent threshold levels. For SU(3), we find many towers of states and partial no-hair behaviors. We explicitly construct the threshold cohomology in the SU(3) theory. We study throughout this paper a subsector of the field theory corresponding to the BMN matrix theory. We also argue that the BMN sector exhibits a black hole like entropy growth at large N.
