Shear viscosity of rotating, hot, and dense spin-half fermionic systems from quantum field theory
Sarthak Satapathy, Rajeev Singh, Pushpa Panday +2
In this study, we calculate the shear viscosity for rotating fermions with spin-half under conditions of high temperature and density. We employ the Kubo formalism, rooted in finit…
Dissipative effects on the propagation of spin modes
Rajeev Singh, Victor E. Ambrus, Radoslaw Ryblewski
In relativistic hydrodynamics with spin, following de Groot--van Leeuwen--van Weert's energy-momentum and spin tensor definitions, we analyze the propagation of spin degrees of fre…
Study of spin polarization dependence on rapidity, transverse momentum, and azimuthal angle
Wojciech Florkowski, Radoslaw Ryblewski, Rajeev Singh
We investigate the spacetime evolution of spin polarization within a hydrodynamic framework based on the de Groot--van Leeuwen--van Weert expressions for energy-momentum and spin t…
Theoretical aspects of relativistic spin hydrodynamics coupled with electromagnetic fields
Rajeev Singh, Masoud Shokri, S. M. A. Tabatabaee
We expand the classical phase-space distribution function to incorporate couplings between spin and electromagnetic fields. This extension has led to the derivation of modified con…
