Polarization dependence of the I¨• meson from finite-temperature QCD sum rules

Hidefumi Matsuda, Philipp Gubler, Koichi Hattori

We study the I¨• meson at finite temperature and finite momentum using QCD sum rules. The presence of medium breaks the Lorentz invariance, and induces distinct in-medium modifica…

Achieving angular-momentum conservation with physics-informed neural networks in computational relativistic spin hydrodynamics

Hidefumi Matsuda, Koichi Hattori, Koichi Murase

We propose physics-informed neural networks (PINNs) as a numerical solver for relativistic spin hydrodynamics and demonstrate that the total angular momentum, i.e., the sum of orbi…

Physics-informed neural networks for angular-momentum conservation in computational relativistic spin hydrodynamics

Hidefumi Matsuda, Koichi Hattori, Koichi Murase

Theoretical developments in relativistic spin hydrodynamics, which describes the macroscopic transport of spin angular momentum alongside other fundamental conserved quantities, ha…
