  We put forward a practical nonequilibrium Green's function (NEGF) scheme to
perform real-time evolutions of many-body interacting systems driven out of
equilibrium by external fields. CHEERS is a computational tool to solve the
NEGF equation of motion in the so called generalized Kadanoff-Baym ansatz and
it can be used for model systems as well as first-principles Hamiltonians.
Dynamical correlation (or memory) effects are added to the Hartree-Fock
dynamics through a many-body self-energy. Applications to time-dependent
quantum transport, time-resolved photoabsorption and other ultrafast phenomena
are discussed.
