Full molecular dynamics simulations of a single trapped ion in a neutral bath
Saajid Chowdhury, Ruiren Shi, Jesús Pérez-Ríos
We present full molecular dynamics simulations that explicitly incorporate the simultaneous interactions between a trapped ion and a bath of neutral atoms. In contrast to conventio…

Chaotic scattering and heating in cold ion-atom collisions: two sides of the same coin
Saajid Chowdhury, Jesús Pérez Ríos
We study the classical dynamics of a Paul-trapped ion in a low-density bath of atoms above 1 . We find that lower energy collisions with more massive atoms, especially…

GPU-Accelerated MATLAB Software for Atom-Ion Dynamics
Saajid Chowdhury, Jesús Pérez-Ríos
We present a MATLAB script which can use GPU acceleration to simulate a trapped ion interacting with a low-density cloud of atoms. This script, called atomiongpu.m, can massively p…
