  Extending the concepts of light-front field theory to quantum statistics
provides a novel approach towards nuclear matter under extreme conditions. Such
conditions exist, e.g., in neutron stars or in the early stage of our universe.
They are experimentally expected to occur in heavy ion collisions, e.g., at
RHIC and accelerators to be build at GSI and CERN. Light-front field theory is
particularly suited, since it is based on a relativistic Hamiltonian approach.
It allows us to treat the perturbative as well as the nonperturbative regime of
QCD and also correlations that emerge as a field of few-body physics and is
important for hadronization. Last but not least the Hamiltonian approach is
useful for nonequilibrium processes by utilizing, e.g., the formalism of
nonequilibrium statistical operators.
