Global equilibrium at order : pseudo-gauge ambiguity, Maxwell relations, and thermodynamic consistency

Asaad Daher, David Wagner, Masoud Shokri +1

We study massive spin- Boltzmann particles in global thermodynamic equilibrium with rotation and acceleration, consistently including quantum corrections up to order $\mathcal…

Formulation of Relativistic Dissipative Spin Hydrodynamics

Asaad Daher

The primary objective of this thesis is to develop a consistent theoretical framework of dissipative hydrodynamics for a relativistic fluid with spin - hereafter referred to as rel…

Dissipative currents and transport coefficients in relativistic spin hydrodynamics

Asaad Daher, Xin-Li Sheng, David Wagner +1

We determine the form of dissipative currents at the first order in relativistic spin hydrodynamics with finite chemical potential including gradients of the spin potential. Taking…

Quasiparticle second-order dissipative hydrodynamics at finite chemical potential

Asaad Daher, Leonardo Tinti, Amaresh Jaiswal +1

We extend the derivation of second-order relativistic viscous hydrodynamics to incorporate the effects of baryon current, a non-vanishing chemical potential, and a realistic equati…

Stability and causality of rest frame modes in second-order spin hydrodynamics

Asaad Daher, Wojciech Florkowski, Radoslaw Ryblewski +1

We analyze the low- and high-momentum rest frame modes in the second-order spin hydrodynamics and check the asymptotic causality of the theory. A truncation scheme of the Israel-St…

Stability constraint for spin equation of state

Asaad Daher, Wojciech Florkowski, Radoslaw Ryblewski

A generalized Frenkel condition is proposed for use in spin hydrodynamics to relate the spin density and spin polarization (or spin chemical potential) tensors. It allows for indep…

Entropy current and entropy production in relativistic spin hydrodynamics

Francesco Becattini, Asaad Daher, Xin-Li Sheng

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…

Relativistic second-order spin hydrodynamics: an entropy-current analysis

Rajesh Biswas, Asaad Daher, Arpan Das +2

We present a new derivation of Israel-Stewart-like relativistic second-order dissipative spin hydrodynamic equations using the entropy current approach. In our analysis, we conside…

Boost invariant spin hydrodynamics within the first order in derivative expansion

Rajesh Biswas, Asaad Daher, Arpan Das +2

Boost-invariant equations of spin hydrodynamics confined to the first-order terms in gradients are numerically solved. The spin equation of state, relating the spin density tensor…

Stability studies of first order spin-hydrodynamic frameworks

Asaad Daher, Arpan Das, Radoslaw Ryblewski

We study the stability of first-order dissipative spin-hydrodynamic frameworks. We considered two different first-order dissipative spin-hydrodynamic frameworks. The first one cons…

Canonical and phenomenological formulations of spin hydrodynamics

Asaad Daher, Arpan Das, Wojciech Florkowski +1

Two formulations of relativistic hydrodynamics of particles with spin 1/2 are compared. The first approach, dubbed the canonical one, uses expressions for the energy-momentum and s…
