Spin alignment, tensor polarizabilities, and local equilibrium for spin-1 particles

Wojciech Florkowski, Sudip Kumar Kar, Valeriya Mykhaylova

Different bases for the spin-1 density matrix are discussed to clarify the connection between its components and observables measured in heavy-ion collisions. The theoretical advan…

Nonlinear causality and stability of perfect spin hydrodynamics and its nonperturbative character

Samapan Bhadury, Zbigniew Drogosz, Wojciech Florkowski +2

Four formulations of perfect spin hydrodynamics for spin-1/2 particles, distinguished by their treatment of spin (classical vs. quantum) and by the underlying particle statistics (…

Local equilibrium Wigner function for spin-1/2 particles

Samapan Bhadury, Zbigniew Drogosz, Wojciech Florkowski +2

Formal connections between the spin density matrix and the Wigner function for spin-1/2 particles forming a relativistic gas are explored to determine their general structures. The…

Exact Wigner function for chiral spirals

Samapan Bhadury, Wojciech Florkowski, Sudip Kumar Kar +1

The exact solution of the Dirac equation for fermions coupled to an external periodic chiral condensate (chiral spiral) is used to obtain the exact formula for the Wigner function…

Spin hydrodynamics -- recent developments

Samapan Bhadury, Zbigniew Drogosz, Wojciech Florkowski +1

After briefly touching on relativistic hydrodynamics, we provide a detailed description of recent developments in spin hydrodynamics. We discuss the theory of perfect spin hydrodyn…

Application range of perfect spin hydrodynamics

Zbigniew Drogosz, Wojciech Florkowski, Valeriya Mykhaylova

The application range of perfect spin hydrodynamics is studied in two cases: one based on the classical spin description and the other using a quantum spin density matrix (Wigner f…
