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 (…
Quarkonium in a QCD medium with momentum-dependent relaxation time
Sunny Kumar Singh, Samapan Bhadury, Ritesh Ghosh +1
In this study, we explore the properties of quarkonia in a hot QCD medium using a newly proposed collision kernel that consistently incorporates the particle's momentum dependence…
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…
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…
Quasi-particle hydrodynamics with momentum-dependent relaxation time
Arghya Mukherjee, Samapan Bhadury, Pracheta Singha
We formulate the relativistic dissipative hydrodynamics of a system of quasi-particles from the Boltzmann equation within the ambit of relaxation time approximation with modified c…
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…
Relativistic spin hydrodynamics from novel relaxation time approximation
Samapan Bhadury
With the help of a semi-classical kinetic theory, a new collision kernel is proposed, which simultaneously conserves the energy-momentum tensor and the spin tensor of a relativisti…
Particle number diffusion in second-order relativistic dissipative hydrodynamics with momentum-dependent relaxation time
Sunny Kumar Singh, Samapan Bhadury, Manu Kurian +1
This article explores particle number diffusion in relativistic hydrodynamics using kinetic theory with a modified collision kernel that incorporates the momentum dependence of the…
