Adiabatic confinement and escape in an open billiard

Matheus Rolim Sales, Leonardo Costa de Souza, Ricardo Luiz Viana +2

We introduce a stationary, field-free billiard that reproduces the adiabatic confinement mechanism of a magnetic mirror through boundary geometry alone. Rapid transverse reflection…

Recurrence time entropy and weak chaos in Hamiltonian flows

Matheus Rolim Sales, Leonardo Costa de Souza, Iberê Luiz Caldas +2

Stickiness in mixed Hamiltonian systems causes chaotic trajectories to remain temporarily trapped near regular structures, making it difficult to distinguish regular, weakly chaoti…

On the dynamical and statistical properties of a quartic mean-field Hamiltonian model

Matheus Rolim Sales, Edson Denis Leonel, Chris G. Antonopoulos

Mean-field systems provide a natural framework in which collective effects persist as the number of degrees of freedom N increases, raising fundamental questions about the emergenc…

pynamicalsys: A Python toolkit for the analysis of dynamical systems

Matheus Rolim Sales, Leonardo Costa de Souza, Daniel Borin +6

Since Lorenz's seminal work on a simplified weather model, the numerical analysis of nonlinear dynamical systems has become one of the main subjects of research in physics. Despite…

Characterizing and quantifying weak chaos in fractional dynamics

Daniel Borin, José Danilo Szezech, Matheus Rolim Sales

A particularly intriguing and unique feature of fractional dynamical systems is the cascade of bifurcations type trajectories (CBTT). We examine the CBTTs in a generalized version…

Ratchet current and scaling properties in a nontwist mapping

Matheus Rolim Sales, Daniel Borin, Leonardo Costa de Souza +4

We investigate the transport of particles in the chaotic component of phase space for a two-dimensional, area-preserving nontwist map. The survival probability for particles within…

Fractional dynamics and recurrence analysis in cancer model

Enrique C. Gabrick, Matheus R. Sales, Elaheh Sayari +8

In this work, we analyze the effects of fractional derivatives in the chaotic dynamics of a cancer model. We begin by studying the dynamics of a standard model, {\it i.e.}, with in…
