Abstract We study the mass spectra and spin alignment of vector meson J/ψ in a thermal magnetized background using a generalized theoretical framework based on gauge/gravity duality. Utilizing a soft wall model for the QGP background and a massive v

Abstract Based on the Nambu–Jona–Lasinio (NJL) model, we develop a framework for calculating the spin alignment of vector mesons and applied it to study $$\phi $$ ϕ mesons in a magnetic field. We calculate mass spectra for $$\phi $$ ϕ mesons an

We use a first-principle quantum-statistical method to derive the expression of the entropy production rate in relativistic spin hydrodynamics. We show that the entropy current is not uniquely defined and can be changed by means of entropy-gauge tran

We have calculated the directed flow v_{1} and charge-dependent directed flow Δv_{1} of pions and protons in Au+Au collisions at sqrt[s_{NN}]=200 GeV by solving the coupled Boltzmann-Maxwell equations self-consistently. Our numerical results show th

We use the method of field decomposition, a widely used technique in relativistic magnetohydrodynamics, to study the small velocity approximation (SVA) of the Lorentz transformation in Maxwell equations for slowly moving media. The “deformed” Max

We construct a matrix-valued spin-dependent distribution function (MVSD) for massive spin-1/2 fermions and study its properties under Lorentz transformations. Such transformations result in a Wigner rotation in spin space and in a nontrivial matrix-v

We study the space-averaged electromagnetic (EM) fields weighted by the energy density in the central regions of heavy-ion collisions. These average quantities can serve as a barometer for the magnetic-field induced effects such as the magnetic effec

We derive the Boltzmann equation and the collision kernel for massive spin-$1/2$ particles, using the Wigner-function formalism and employing an expansion in powers of $\ensuremath{\hbar}$. The phase space is enlarged to include a variable related to
