Euler-Heisenberg Lagrangian under an axial gauge field
Patrick Copinger, Koichi Hattori, Di-Lun Yang
Augmentations to the Euler-Heisenberg Lagrangian (QED one-loop effective action in homogeneous electromagnetic fields) under a constant background axial gauge are examined. Two spe…
New developments in relativistic magnetohydrodynamics
Koichi Hattori, Masaru Hongo, Xu-Guang Huang
Relativistic magnetohydrodynamics (RMHD) provides an extremely useful description of the low-energy long-wavelength phenomena in a variety of physical systems from quark-gluon plas…
Gyrohydrodynamics: Relativistic spinful fluid with strong vorticity
Zheng Cao, Koichi Hattori, Masaru Hongo +2
We develop a relativistic (quasi-)hydrodynamic framework, dubbed the gyrohydrodynamics, to describe fluid dynamics of many-body systems with spin under strong vorticity based on en…
Revisiting relativistic magnetohydrodynamics from quantum electrodynamics
Masaru Hongo, Koichi Hattori
We provide a statistical mechanical derivation of relativistic magnetohydrodynamics on the basis of the -dimensional quantum electrodynamics; the system endowed with the mag…
Fate of spin polarization in a relativistic fluid: An entropy-current analysis
Koichi Hattori, Masaru Hongo, Xu-Guang Huang +2
We derive relativistic hydrodynamic equations with a dynamical spin degree of freedom on the basis of an entropy-current analysis. The first and second laws of local thermodynamics…
MagnetoHydrodynamics with chiral anomaly: phases of collective excitations and instabilities
Koichi Hattori, Yuji Hirono, Ho-Ung Yee +1
We study the relativistic hydrodynamics with chiral anomaly and dynamical electromagnetic fields, namely Chiral MagnetoHydroDynamics (CMHD). We formulate CMHD as a low-energy effec…
