9/10 12:30 Prof. Norihiro Iizuka (NTHU) Genuine Multi-Entropy: From Black Holes to Topological Order (R521, 5F, General Building II, Nat'l Tsing Hua Univ.)
******** CTCD/NTHU HEP Seminar ********
Speaker : Prof. Norihiro Iizuka (NTHU)
Title ：Genuine Multi-Entropy: From Black Holes to Topological Order
Time ：12:30-13:30, Thursday, 2026/9/10
Place ：R521, 5F, General Building II, Nat'l Tsing Hua Univ.
Host ： Prof. Kingman Cheung (NTHU)
Abstract:
Multipartite entanglement is expected to play an important role in many-body quantum systems, quantum gravity, and topological phases, yet a general and physically useful diagnostic has remained elusive. In this talk, I will introduce genuine multi-entropy (GM), a new probe of genuine multipartite entanglement obtained from multi-entropies. After explaining the basic idea and its main properties, I will review recent applications of GM to black holes and holography, including black hole multi-entropy curves, a multipartite generalization of the Page curve, holographic multipartite entanglement, and junction laws. If time permits, I will also discuss recent developments in spin systems and topological phases, including the toric code, illustrating that GM provides a common framework for studying multipartite entanglement across diverse areas of physics.
