Constructing perfect spin-1 hydrodynamics from Boltzmann to Bose-Einstein statistics
Sudip Kumar Kar, Valeriya Mykhaylova
We derive thermodynamic currents for a perfect fluid of massive spin-1 particles obeying Bose-Einstein statistics within the Wigner-function approach. Using a covariant spin densit…
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 (…
Fermi-Dirac Wigner function for massive spin-1/2 particles in local equilibrium
Sudip Kumar Kar, Valeriya Mykhaylova
A recently proposed Boltzmann local equilibrium Wigner function for massive spin-1/2 particles is generalized to the case of Fermi-Dirac statistics. The resulting formula ensures t…
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…
