Time-dependent Trapped Plasmas: Nonlinear Dynamics, Symmetries and Invariants
Thonimar V. Alencar, Luiz Gustavo Ferreira Soares, Ronaldo Thibes
We investigate the nonlinear dynamics of a single-component plasma confined in a time-dependent harmonic trap regarding aspects of symmetry and invariant functions. The system is d…

Curvature--Radiation Geometries Across the Second CHIME/FRB Fast Radio Burst Population
Thonimar V. Alencar, Jéferson A. S. Fortunato, Wiliam S. Hipólito-Ricaldi
We present a population-level spectral analysis of fast radio bursts from the second CHIME/FRB catalog using three curvature-radiation-motivated templates: point-source, one-dimens…
