Interacting tunneling model for two-level systems in amorphous materials and its predictions for their dephasing and noise in superconducting microresonators

Interacting tunneling model for two-level systems in amorphous materials and its predictions for their dephasing and noise in superconducting microresonators

We use a tunneling model for two-level systems in insulators that takes into account the interaction between them and a slow power-law dependence of their density of states. We show that the predictions of this model are in a perfect agreement with the recent studies of the noise in high …
