Massive vector field perturbations in the Schwarzschild spacetime from supersymmetric gauge theory
Xian-Hui Ge, Masataka Matsumoto, Kilar Zhang
We unify the dynamics of massive vector (Proca) fields in Schwarzschild spacetime with supersymmetric gauge theories through the Seiberg-Witten/quasinormal mode (SW/QNM) duality. B…

Quantum Chaos, Thermalization, and Non-locality
Masataka Matsumoto, Shuta Nakajima, Masahiro Nozaki +1
In this paper, we numerically investigate whether quantum thermalization occurs during the time evolution induced by a non-local Hamiltonian whose spectra exhibit integrability. Th…

Non-Linear Dynamics and Critical Phenomena in the Holographic Landscape of Weyl Semimetals
Masataka Matsumoto, Mirmani Mirjalali, Ali Vahedi
This study presents a detailed analysis of critical phenomena in a holographic Weyl semi-metal (WSM) using the brane configuration. The research explores the non-linear res…
