Diffusion of multiple conserved charges from entropy production
Samapan Bhadury, Arpan Das, Sandeep Chatterjee +1
We derive dissipative relativistic hydrodynamic equations in the presence of multiple conserved charges, i.e., baryon number (), electric charge (), and strangeness (), us…
Hyperon longitudinal polarization and vector meson spin alignment in a thermal model for heavy-ion collisions
Soham Banerjee, Samapan Bhadury, Wojciech Florkowski +2
The concept of a common local spin equilibrium for both spin-1/2 and spin-1 particles is incorporated into a thermal model of particle production in heavy-ion collisions at the top…
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…
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…
