Causal Relativistic Fluid Dynamics
Relativisitic fl uid dynamics relativistic kinetic theory expand- ing medium
2011/10/18
We derive causal relativistic fluid dynamical equations from the relaxation model of kinetic theory as in a procedure previously applied in the case of non-relativistic rarefied gases. By treating spa...
A Fast Numerical Scheme for Causal Relativistic Hydrodynamics with Dissipation
relativistic hydrodynamics relativistic dissipation relativity kinetic theory methods: numerical
2011/9/13
In this paper, we develop a stable and fast numerical scheme for relativistic dissipative hydrodynamics based on Israel-Stewart theory. Israel-Stewart theory is a stable and causal description of diss...
On the final definition of the causal boundary and its relation with the conformal boundary

2010/3/19
The notion of causal boundary $\partial M$ for a strongly causal spacetime $M$ has been a controversial topic along last decades: on one hand, some attempted definitions were not fully consistent, on ...
Global causal propagator for the Klein-Gordon equation on a class of supersymmetric AdS backgrounds
Klein-Gordon equation supersymmetric AdS backgrounds spectral-theoretic techniques
2010/3/19
We analyze the Cauchy problem for the Klein-Gordon equation on the type IIB supergravity backgrounds $AdS^5 \times Y^{p,q}$, where $Y^{p,q}$ is any of the Sasaki-Einstein 5-manifolds recently discover...
Local causal structures, Hadamard states and the principle of local covariance in quantum field theory
quantum field theory local covariance
2010/3/18
In the framework of the algebraic formulation, we discuss and analyse some new features of the local structure of a real scalar quantum field theory in a strongly causal spacetime. In particular we us...
We investigate the causal temperature profiles in a recent model of a radiating star undergoing dissipative gravitational collapse without the formation of a horizon. It is shown that this simple exac...
