Deep squeezing or cooling the fluctuations of a parametric resonator using feedback
Adriano A. Batista, Raoni S. N. Moreira, A. A. Lisboa de Souza
Here we analyze ways to achieve deep subthreshold parametric squeezing or cooling of a single degree-of-freedom parametric resonator enhanced by a lock-in amplifier feedback loop.…
Feedback-enhanced squeezing or cooling of fluctuations in a parametric resonator
Adriano A. Batista
Here we analyse ways to achieve deep subthreshold parametric squeezing of fluctuations beyond the ~dB limit of single degree-of-freedom parametric resonators. One way of accomp…
Deep noise squeezing in parametrically driven resonators
Adriano A. Batista, Raoni S. N. Moreira, A. A. Lisboa de Souza
Here we investigate white noise squeezing in the frequency domain of classical parametrically-driven resonators with added noise. We use Green's functions to analyse the response o…
Gain and noise spectral density in an electronic parametric amplifier with added white noise
Adriano A. Batista, A. A. Lisboa de Souza
In this paper, we discuss the behavior of a linear classical parametric amplifier (PA) in the presence of white noise and give theoretical estimates of the noise spectral density b…
