Information geometry encoded in bulk geometry
Asato Tsuchiya, Kazushi Yamashiro
We study how information geometry is described by bulk geometry in the gauge/gravity correspondence. We consider a quantum information metric that measures the distance between the…

Renormalization on the fuzzy sphere
Kohta Hatakeyama, Asato Tsuchiya, Kazushi Yamashiro
We study renormalization on the fuzzy sphere, which is a typical example of non-commutative spaces. We numerically simulate a scalar field theory on the fuzzy sphere, which is desc…

Renormalization on the fuzzy sphere
Kohta Hatakeyama, Asato Tsuchiya, Kazushi Yamashiro
We study renormalization on the fuzzy sphere. We numerically simulate a scalar field theory on it, which is described by a Hermitian matrix model. We show that correlation function…
