- Abstract summary: In combined potential wells with a static Sauter potential well and a frequency modulated one, the modulated amplitude has a large effect on the number of created pairs.
It implies that for a slowly oscillating Sauter potential well, the chirp effect through the frequency modulation is better than adding a static potential well to improve the pair production.

- Abstract: Electron-positron pair production in frequency modulated Sauter potential
wells is investigated in the framework of the computational quantum field
theory. In combined potential wells with a static Sauter potential well and a
frequency modulated oscillating one, the modulated amplitude has a large effect
on the number of created pairs. The optimal modulation amplitude of frequency
at different center frequencies is obtained, which increases the number of
electrons at about two times. However, for a single oscillating potential well
with frequency modulation, chirp effect is sensitive to the center frequency,
and the number of electrons can be enhanced even to four orders of magnitude at
a regime of low center frequency. It implies that for a slowly oscillating
Sauter potential well, the chirp effect through the frequency modulation is
better than adding a static potential well to improve the pair production.

It is found that the momentum spectrum (the reduced particle number) is more sensitive to the modulated amplitude (modulated frequency) of the phase.
For high central frequency field, an extremely good symmetry in momentum spectrum is found while it is destroyed severely when the modulated amplitude becomes large.
Two interesting features are revealed for the reduced particle number, i.e., the optimal modulation parameters are found and the same particle number can be got through different set of modulation parameters.

We develop a general theoretical framework to dynamically engineer quantum correlations in the frequency-comb emission from an array of superconducting qubits in a waveguide.
We demonstrate, that when the resonance of the two qubits are periodically modulated with a $pi$ phase shift, it is possible to realize simultaneous bunching and antibunching in cross-correlations of the scattered photons from different sidebands.
