Query: Shear viscosity, cavitation and hydrodynamics at LHC   We study evolution of quark-gluon matter in the ultrarelativistic heavy-ion
collisions within the frame work of relativistic second-order viscous
hydrodynamics. In particular, by using the various prescriptions of a
temperature-dependent shear viscosity to the entropy ratio, we show that the
hydrodynamic description of the relativistic fluid become invalid due to the
phenomenon of cavitation. For most of the initial conditions relevant for LHC,
the cavitation sets in very early during the evolution of the hydrodynamics in
time $\lesssim 2 $fm/c. The cavitation in this case is entirely driven by the
large values of shear viscosity. Moreover we also demonstrate that the
conformal term used in equations of the relativistic dissipative hydrodynamic
can influence the cavitation time.
