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…
Charm Quark Kinetics in Heavy Ion Collisions
Valeriya Mykhaylova, Krzysztof Redlich, Chihiro Sasaki
We study the evolution of charm quarks in hot QCD matter with quark flavors by analyzing the charm production rate and the time dependence of their abundance. M…
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…
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…
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…
Proceedings of the IFJ PAN Particle Physics Summer Student Alumni Conference 2022
Derendarz Dominik, Rafal Staszewski, Maciej Trzebinski +13
IFJ PAN PPSS Alumni Conference is organized by the Institute of Nuclear Physics Polish Academy of Sciences (IFJ PAN). It is addressed to: participants of previous editions of Parti…
Impact of quark quasiparticles on transport coefficients in hot QCD
Valeriya Mykhaylova, Chihiro Sasaki
We study the bulk and shear viscosity and the electrical conductivity in a quasiparticle approach to Yang-Mills theory and QCD with light and strange quarks to assess the dynamical…
Quark Flavour Dependence of the Shear Viscosity in a Quasiparticle Model
Valeriya Mykhaylova, Marcus Bluhm, Krzysztof Redlich +1
We study the temperature-dependence of the shear viscosity to entropy density ratio in pure Yang-Mills theory and in QCD with light and strange quarks within kinetic theory in the…
