Amplification in parametrically-driven resonators near instability based on Floquet theory and Green's functions
Adriano A. Batista
Here we use Floquet theory to calculate the response of parametrically-driven time-periodic systems near the onset of parametric instability to an added external ac signal or white…
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…
An epidemiological compartmental model with automated parameter estimation and forecasting of the spread of COVID-19 with analysis of data from Germany and Brazil
Adriano A. Batista, Severino Horácio da Silva
In this work, we adapt the epidemiological SIR model to study the evolution of the dissemination of COVID-19 in Germany and Brazil (nationally, in the State of Paraiba, and in the…
Frequency-comb response of a parametrically-driven Duffing oscillator to a small added ac excitation
Adriano A. Batista, A. A. Lisboa de Souza
Here we present a one-degree-of-freedom model of a nonlinear parametrically-driven resonator in the presence of a small added ac signal that has spectral responses similar to a fre…
Rabi oscillations in two-level systems beyond the rotating-wave approximation
Adriano A. Batista
Here we use perturbation techniques based on the averaging method to investigate Rabi oscillations in cw and pulse-driven two-level systems (TLS's). By going beyond the rotating-wa…
Heating and thermal squeezing in parametrically-driven oscillators with added noise
Adriano A. Batista
In this paper we report a theoretical model based on Green functions, Floquet theory and averaging techniques up to second order that describes the dynamics of parametrically-drive…
