Quantum Primordial Standard Clocks

Chen, Xingang, Namjoo, Mohammad Hossein, Wang, Yi

Understand

In this paper, we point out and study a generic type of signals existing in the primordial universe models, which can be used to model-independently distinguish the inflation scenario from alternatives.

These signals are generated by massive fields that function as standard clocks.
The role of massive fields as standard clocks has been realized in previous works.
Although the existence of such massive fields is generic, the previous realizations require sharp features to classically excite the oscillations of the massive clock fields.
