  We study the effects of a finite chemical potential on the occurrence of
cavitation in a quark gluon plasma (QGP). We solve the evolution equations of
second order viscous relativistic hydrodynamics using three different equations
of state. The first one was derived in lattice QCD and represents QGP at zero
chemical potential. It was previously used in the study of cavitation. The
second equation of state also comes from lattice QCD and is a recent
parametrization of the QGP at finite chemical potential. The third one is
similar to the MIT equation of state with chemical potential and includes
nonperturbative effects through the gluon condensates. We conclude that at
finite chemical potential cavitation in the QGP occurs earlier than at zero
chemical potential. We also consider transport coefficients from a holographic
model of a non-conformal QGP at zero chemical potential. In this case
cavitation does not occur.
