Quantum fields in the future Rindler wedge

We consider interacting massive scalar quantum field theory in the future Rindler wedge. This is a model example of curved space-time. Using this simple example, we show how dynamics correlation functions depends on choice initial Cauchy surface, basis modes, and state built using corresponding creation annihilation operators. which modes wedge respects Poincar\'e symmetry. However, do not restrict our attention only to these ground state.
