  We propose a real time holographic framework to study thermalization
processes of a family of QFT excited states. The construction builds on
Skenderis-van Rees's holographic duals to QFT Schwinger-Keldysh complex-time
ordered paths. Thermalization is explored choosing a set of observables $F_n$
which essentially isolate the excited state contribution. Focusing on theories
defined on compact manifolds and with excited states defined in terms of
Euclidean path integrals, we identify boundary conditions that allow to avoid
any number of modes in the initial field state. In the large conformal
dimensions regime, we give precise prescriptions on how to compute the
observables in terms of bulk geodesics.
