Visualizing Mathieu-Type Dynamics in a Tabletop Magnetic Trap: A Coil-Driven Parametric Oscillator
William Ho, Anna Klales, Daniel Davis +4
We present a tabletop demonstration of dynamic stabilization and ponderomotive-like trapping using a pair of sinusoidally-driven anti-Helmholtz coils and a suspended permanent magn…

Demonstrating Dynamic Stability in Paul Traps: Exploring Rotating Saddles with Liquid Nitrogen Droplets
Laurel Barnett, Aidan Carey, Robert Hart +3
Rotating saddle potentials provide a compelling visual demonstration of dynamic stability, widely used in undergraduate physics as mechanical analogs to the RF Paul trap. Tradition…

The asymmetric rotating saddle potential as a mechanical analog to the RF Paul trap
Aidan Carey, Laurel Barnett, Robert Hart +3
Under specific conditions, a rotating saddle potential can confine the motion of a particle on its surface. This time-varying hyperbolic potential shares key characteristics with t…
