Effective field theory for hydrodynamics: Wess-Zumino term and anomalies in two spacetime dimensions
Effective field theory hydrodynamics:anomalies spacetime dimensions
2011/10/14
We develop the formalism that incorporates quantum anomalies in the effective field theory of non-dissipative fluids. We consider the effect of adding a Wess-Zumino-like term to the low-energy effecti...
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...
A new multi-dimensional general relativistic neutrino hydrodynamics code for core-collapse supernovae. I. Method and code tests in spherical symmetry

2010/3/19
We present a new general relativistic (GR) code for hydrodynamic supernova simulations with neutrino transport in spherical and azimuthal symmetry (1D/2D). The code is a combination of the CoCoNuT hyd...

Molecular clouds have a hierarchical structure from few tens of
parsecs for giants to few tenth of a parsec for proto-stellar cores. Nowadays, our
observational techniques are so advanced that it ha...
