Relativistic second-order spin hydrodynamics: an entropy-current analysis
Rajesh Biswas, Asaad Daher, Arpan Das +2
We present a new derivation of Israel-Stewart-like relativistic second-order dissipative spin hydrodynamic equations using the entropy current approach. In our analysis, we conside…
Pseudo-gauge dependence of quantum fluctuations of energy in a hot relativistic gas of fermions
Arpan Das, Wojciech Florkowski, Radoslaw Ryblewski +1
Explicit expressions for quantum fluctuations of energy in subsystems of a hot relativistic gas of spin- particles are derived. The results depend on the form of the energy-mo…
Dark matter admixed neutron star properties in the light of gravitational wave observations: a two fluid approach
Arpan Das, Tuhin Malik, Alekha C. Nayak
We consider the effect of density dependent dark matter on the neutron star mass, radius, and tidal deformability. Nuclear matter (normal matter) as well as the fermionic dark matt…
Correspondence between Israel-Stewart and first-order causal and stable hydrodynamics for Bjorken-expanding baryon-rich systems with vanishing particle masses
Arpan Das, Wojciech Florkowski, Radoslaw Ryblewski
We obtain an exact correspondence between the dynamical equations in Israel-Stewart (IS) theory and first-order causal and stable (FOCS) hydrodynamics for a boost-invariant system…
Correspondence between Israel-Stewart and first-order casual and stable hydrodynamics for the boost-invariant massive case with zero baryon density
Arpan Das, Wojciech Florkowski, Radoslaw Ryblewski
Exact correspondence between Israel-Stewart theory and first-order causal and stable hydrodynamics is established for the boost-invariant massive case with zero baryon density and…
Equivalence between first-order causal and stable hydrodynamics and Israel-Stewart theory for boost-invariant systems with a constant relaxation time
Arpan Das, Wojciech Florkowski, Jorge Noronha +1
We show that the recently formulated causal and stable first-order hydrodynamics has the same dynamics as Israel-Stewart theory for boost-invariant, Bjorken expanding systems with…
