摘要：
Tom and Goodison [5] have shown that for generic values of q, gravitationally induced particle creation is impossible in the ordinary vacuum state. Here we consider the evolution of a deformed scalar field in a curved spacetime and observe that if the field is either represented by a coherent state or a squeezed state, there is a change in the energy density of the field indicating the possibility of particle creation.
