Complex spectral analysis and test function spaces    [PDF]

Sungyun Kim, Gonzalo Ordonez

We consider complex spectrum of unstable model Hamiltonian and its physically meaningful regions. It is shown that physically meaningful regions are obtained by taking only Hardy class below part of test functions. Through specific model it is shown that this complex eigenstates with restricted test functions show causality and represent physically meaningful regions in time evolution.
