摘要

In holographic theories with nilpotent supercharges, BPS states can be classified into fortuitous states and monotonous states. Fortuity distinguishes typical black hole micro-states from those of horizonless geometries (monotonous). I will explain this classification in SUSY SYK models. Fortuitous states also like to concentrate at some particular charge sectors. I will propose a conjecture called ‘’supercharge chaos’’ to account for this concentration phenomena and explain an index calculation to locate the particular charge where the concentration occurs. Along the way I will mention the features of N=2 SUSY SYK models and their BPS sector. This is a joint work with Chi Ming Chang, Yiming Chen and Zhenbin Yang.
