This paper describes the quasi-steady regime attained by a rapidly rotating vortex after a wave packet has interacted with it. We consider singular, nonlinear, helical, and shear asymmetric modes within a linearly stable, ...

Tsallis maximum entropy distributions provide useful tools for the study of a wide range of scenarios in mathematics, physics, and other fields. Here we apply a Tsallis maximum entropy ansatz, the q-Gaussian, to obtain ...

We provide a full characterization of two-electron nondispersive wave packets found in the Floquet spectrum of driven helium. These quantum objects which propagate along periodic trajectories of the classical three-body ...
