Analogue cosmology in relativistic fluids

Vrijeme: 14 sati c.t.
Mjesto: IRB, predavaona I krila
Sazetak:
Due to the fact that certain aspects of general relativity are
generic features of curved spacetime, various gravitational phenomena,
such as apparent and event horizons and Hawking radiation,
can be studied using analog models of gravity. In contrast to
general relativity, where geometry of a spacetime is determined by
the Einstein equations, in analog models geometry and evolution of
analog spacetime are determined by the equations of fluid mechanics.
In particular, we apply the formalism of analog gravity to
the expanding hadronic fluid. The analog metric tensor depends
locally on the soft pion dispersion relation and the four-velocity
of the fluid. The analog expanding spacetime takes the form of an
FRW universe, with the apparent and trapping horizons defined
in the standard way.
