3/5 12:30 Dr. Marti Rossello Gomez (AS) Finite-N holography and the Giant Graviton Expansion. (R521, 5F, General Building II, Nat'l Tsing Hua Univ.)
******** CTCD/NTHU HEP Seminar ********
Speaker ：Dr. Marti Rossello Gomez (AS)
Title ：Finite-N holography and the Giant Graviton Expansion
Time ：12:30-13:30, Thursday, 2026/3/5
Place ：R521, 5F, General Building II, Nat'l Tsing Hua Univ.
Host ： Prof. Norihiro Iizuka (NTHU)
Abstract:
The giant graviton expansion reorganizes finite-N indices in superconformal field theories as the large-N result multiplied by a systematic series of finite-N corrections. These corrections have a natural holographic interpretation in terms of branes in the bulk, known as giant gravitons. I will provide a gentle introduction to the topic and then derive the giant graviton expansion for the half-BPS index of N=4 SYM directly from the bulk AdS5xS5, showing that the analytic continuation found in the literature can be understood as an instance of wall-crossing.
