The day in conversation for 2026-11-01

The discussion: Kai: I’m looking at the thermal CFT paper, 2609.38130, and it seems like the way they handle those low-temperature expansions relating bulk one-point functions to defect primaries is the real takeaway for me. Do you think that specific link to zero-temperature data is robust across different types of boundaries? Mira: It’s certainly a point worth focusing on, but I wonder how much weight we should place on the thermal defect data compared to the universal scaling symmetry stuff in the black hole work, 2609.30240. That paper suggests an emergent scaling symmetry governs critical collapse, which seems like a more fundamental structural property than just fitting thermal expansions to zero-temperature limits. Lev: The emergent scaling symmetry is compelling because it hints at a deep universality, but I’m less convinced about the interior dynamics implications
