2 + 1 dimensional hydrodynamics including bulk viscosity: A systematic study

Bulk viscosity in holographic Lifshitz hydrodynamics

We compute the bulk viscosity in holographic models dual to theories with Lifshitz scaling and/or hyperscaling violation, using a generalization of the bulk viscosity formula derived in arXiv:1103.1657 from the null focusing equation. We find that only a class of models with massive vector fields are truly Lifshitz scale invariant, and have a vanishing bulk viscosity. For other holographic mode...

Boost-Invariant (2+1)-Dimensional Anisotropic Hydrodynamics

We present results of the application of the anisotropic hydrodynamics (aHydro) framework to (2+1)dimensional boost-invariant systems. The necessary aHydro dynamical equations are derived by taking moments of the Boltzmann equation using a momentum-space anisotropic one-particle distribution function. We present a derivation of the necessary equations and then proceed to numerical solutions of ...

O ct 2 00 8 A potential including Heaviside function in 1 + 1 dimensional hydrodynamics by Landau

In 1+1 dimensional hydrodynamics originally proposed by Landau, we derive a new potential and distribution function including Heaviside function and investigate its mathematical and physical properties. Using the original distribution derived by Landau, a distribution function found by Srivastava et al., our distribution function, and the Gaussian distribution proposed by Carruthers et al., we ...

Entropy generation in a five-dimensional cosmology admitting bulk viscosity

Bulk viscosity of N = 2 ∗ plasma

We use gauge theory/string theory correspondence to study the bulk viscosity of strongly coupled, mass deformed SU(Nc) N = 4 supersymmetric Yang-Mills plasma, also known as N = 2 gauge theory. For a wide range of masses we confirm the bulk viscosity bound proposed in [1]. For a certain choice of masses, the theory undergoes a phase transition with divergent specific heat cV ∼ |1 − Tc/T |−1/2. W...
