Tom and Goodison [5] have shown that for generic values ofq, gravitationally induced particle creation is impossible in the ordinary vacuum state. Here we consider the evolution of
aq-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. 相似文献

The differences among quon operators, q
a-math oscillator operators and q-deformed oscillator operators are pointed out. The q-deformed ocsillator and q
a-math oscillator are constructed in terms of q
q = 0 quon. 相似文献
