Non-perturbative guiding center model for magnetized plasmas
J. W. Burby, I. A. Maldonado, M. Ruth +1
Perturbative guiding center theory adequately describes the slow drift motion of charged particles in the strongly-magnetized regime characteristic of thermal particle populations…

Physics-guided weak-form discovery of reduced-order models for trapped ultracold hydrodynamics
Reuben R. W. Wang, Daniel Messenger
We study the relaxation of a highly collisional, ultracold but nondegenerate gas of polar molecules. Confined within a harmonic trap, the gas is subject to fluid-gaseous coupled dy…

Weak-Form Inference for Hybrid Dynamical Systems in Ecology
Daniel Messenger, Greg Dwyer, Vanja Dukic
Species subject to predation and environmental threats commonly exhibit variable periods of population boom and bust over long timescales. Understanding and predicting such behavio…
