Optimal ratchet current for elastically interacting particles
Rafael M. da Silva, Cesar Manchein, Marcus W. Beims
In this work we show that optimal ratchet currents of two interacting particles are obtained when stable periodic motion is present. By increasing the coupling strength between ide…
Intermittent stickiness synchronization
Rafael M. da Silva, Cesar Manchein, Marcus W. Beims
This work uses the statistical properties of Finite-Time Lyapunov Exponents (FTLEs) to investigate the Intermittent Stickiness Synchronization (ISS) observed in the mixed phase spa…
Steering multiattractors to overcome parameter inaccuracy and noise effects
Rafael M. da Silva, Nathan S. Nicolau, Cesar Manchein +1
Steering of attractors in multistable systems is used to increase the available parameter domains which lead to stable dynamics in nonlinear physical systems, reducing substantiall…
Exploring conservative islands using correlated and uncorrelated noise
Rafael M. da Silva, Cesar Manchein, Marcus W. Beims
In this work, noise is used to analyze the penetration of regular islands in conservative dynamical systems. For this purpose we use the standard map choosing nonlinearity paramete…
Controlling intermediate dynamics in a family of quadratic maps
Rafael M. da Silva, Cesar Manchein, Marcus W. Beims
The intermediate dynamics of composed one-dimensional maps is used to multiply attractors in phase space and create multiple independent bifurcation diagrams which can split apart.…
Proliferation of stability in phase and parameter spaces of nonlinear systems
Cesar Manchein, Rafael M. da Silva, Marcus W. Beims
In this work we show how the composition of maps allows us to multiply, enlarge and move stable domains in phase and parameter spaces of discrete nonlinear systems. Using Hénon map…
Characterizing Weak Chaos using Time Series of Lyapunov Exponents
R. M. da Silva, C. Manchein, M. W. Beims +1
We investigate chaos in mixed-phase-space Hamiltonian systems using time series of the finite- time Lyapunov exponents. The methodology we propose uses the number of Lyapunov expon…
