Hovering Sets in Near Pseudo-Integrable Hamiltonian Impact Systems
Idan Pazi, Alexandra Zobova, Vered Rom-Kedar
The transition from rotational to discontinuous behavior of the return map of the perturbed oscillators-step system, a paradigm model for a perturbation of a pseudo-integrable Hami…
On the structure of Hamiltonian impact systems
Michal Pnueli, Vered Rom-Kedar
Near-integrability is usually associated with smooth small perturbations of smooth integrable systems. Studying integrable mechanical Hamiltonian flows with impacts that respect th…
On near integrability of some impact systems
Michal Pnueli, Vered Rom-Kedar
A class of Hamiltonian impact systems exhibiting smooth near integrable behavior is presented. The underlying unperturbed model investigated is an integrable, separable, 2 degrees…
Leaky Fermi accelerators
Kushal Shah, Vassili Gelfreich, Vered Rom-Kedar +1
A Fermi accelerator is a billiard with oscillating walls. A leaky accelerator interacts with an environment of an ideal gas at equilibrium by exchange of particles through a small…
New Lagrangian diagnostics for characterizing fluid flow mixing
Ruty Mundel, Erick Fredj, Hezi Gildor +1
A new kind of Lagrangian diagnostic family is proposed and a specific form of it is suggested for characterizing mixing: the maximal extent of a trajectory (MET). It enables the de…
A saddle in a corner - a model of collinear triatomic chemical reactions
L. Lerman, V. Rom-Kedar
A geometrical model which captures the main ingredients governing atom-diatom collinear chemical reactions is proposed. This model is neither near-integrable nor hyperbolic, yet it…
