Title: Special Loci in Field Space: Infinite-Distance Limits in N=2 Quiver Gauge Theories
Abstract: Special loci in the field space of quantum gravity theories provide valuable physical insight. Notable examples include symmetric points in the interior of moduli space and points at infinite distance. In this talk, I will focus on infinite-distance limits of four-dimensional N=2 SU quiver gauge theories with hypermultiplets in bifundamental and fundamental representations, within the context of the holographic swampland program. We use the large-N Hagedorn temperature and the exponential rate $\alpha$ as probes of the emergent bulk physics. We compute the large-N Hagedorn temperature $T_H$ and argue that it identifies the type of string theory underlying the bulk physics, while remaining insensitive to detailed geometric data. We also analyze the exponential rate $\alpha$, which governs how the leading tower of higher-spin currents becomes conserved, and derive sharp bounds on it.
