10/8 12:30 Dr. Ghanashyam Meher (NTU) Local Thermalization of SU(2) Lattice Gauge Fields on Quantum Computers (R521, 5F, General Building II, Nat'l Tsing Hua Univ.)
******** CTCD/NTHU HEP Seminar ********
Speaker : Dr. Ghanashyam Meher (NTU)
Title : Local Thermalization of SU(2) Lattice Gauge Fields on Quantum Computers
Time ：12:30-13:30, Thursday, 2026/10/8
Place ：R521, 5F, General Building II, Nat'l Tsing Hua Univ.
Host ：Prof. Kingman Cheung (NTHU) & Prof. Norihiro Iizuka (NTHU)
Abstract:
I am going to show you how we studied the local thermalization dynamics of a minimally truncated SU(2) pure gauge theory on linear plaquette chains containing up to 151 plaquettes using IBM quantum computers. To characterize the thermalization dynamics, we investigated the time evolution of the entanglement spectrum, Rényi-2 entropy, and anti-flatness for small subsystems. The quantum hardware results obtained after error mitigation agree with classical simulator results for chains of up to 101 plaquettes. These results demonstrate the feasibility of studying local thermalization in non-Abelian lattice gauge theories using current noisy quantum computing platforms.
