Sub-Fluid Models in Dissipative Magneto-Hydrodynamics

Dissipative or Just Nonextensive Hydrodynamics? -nonextensive/dissipative Correspondence

Recently there is renewed interest in dissipative hydrodynamical models [1, 2, 3, 4, 5] prompted by the success of perfect hydrodynamics in describing RHIC data [6] and by recent calculations of transport coefficients of strongly interacting quark-gluon system using the AdS/CFT correspondence [7]. The question is whether dissipative hydrodynamics (d-hydrodynamics) is really needed and how it sh...

Dissipative hydrodynamics and heavy ion collisions

Space-time evolution and subsequent particle production from minimally viscous (η/s=0.08) QGP fluid is studied using the 2nd order Israel-Stewart’s theory of dissipative relativistic fluid. Compared to ideal fluid, energy density or temperature evolves slowly in viscous dynamics. Particle yield at high pT is increased. Elliptic flow on the other hand decreases in viscous dynamics. Minimally vis...

Dissipative effects from transport and viscous hydrodynamics

We compare 2 → 2 covariant transport theory and causal IsraelStewart hydrodynamics in 2+1D longitudinally boost invariant geometry with RHIC-like initial conditions and a conformal ε = 3p equation of state. The pressure evolution in the center of the collision zone and the final differential elliptic flow v2(pT ) from the two theories agree remarkably well for a small shear viscosity to entropy...

Causal Theory of Relativistic Dissipative Hydrodynamics

We present a new formalism for the theory of relativistic dissipative hydrodynamics, where covariance and causality are satisfied by introducing the memory effect in irreversible currents. Our theory has a much simpler structure and thus has several advantages for practical purposes compared to the Israel-Stewart theory (IS). We apply our formalism to the Bjorken model and the results are shown...
