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…
Stochastic resonance and amplification in the ac driven Duffing oscillator with added noise
Adriano A. Batista, A. A. Lisboa de Souza, Raoni S. N. Moreira
Stochastic resonance (SR) is a coherence enhancement effect due to noise that occurs in periodically-driven nonlinear dynamical systems. A very broad range of physical and biologic…
Fock-state superradiance in a cold atomic ensemble
D. F. Barros, L. F. Muñoz-Martínez, L. Ortiz-Gutiérrez +7
A simplified theory for the wavepackets of the photons emitted during the read process of a quantum memory formed by cold atoms is provided. We arrive at analytical expressions for…
Experimental Fock-State Superradiance
L. G. O. Gutierrez, L. F. M. Martinez, D. F. Barros +6
Superradiance in an ensemble of atoms leads to the collective enhancement of radiation in a particular mode shared by the atoms in their spontaneous decay from an excited state. Th…
Signal to noise ratio in parametrically-driven oscillators
Adriano A. Batista, Raoni S. N. Moreira
Here we report a theoretical model based on Green's functions and averaging techniques that gives ana- lytical estimates to the signal to noise ratio (SNR) near the first parametri…
