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…
Self-limiting electrostriction of a single ion in an ultracold polar gas: From mesoscopic ions to crystalline molecular rings
Ruiren Shi, Saajid Chowdhury, Leon Karpa +1
We investigate the self-assembly of polar molecules around a single ion immersed in an ultracold, dilute two-dimensional molecular gas. The ion aligns and attracts the molecules th…
Coordination-driven magic numbers in protonated argon clusters
Saajid Chowdhury, María Judit Montes de Oca-Estévez, Florian Foitzik +6
The structural properties of rare-gas clusters can be primarily described by a simple sphere packing model or by pairwise interactions. Remarkably, adding a single proton yields a…
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…
Ion solvation in atomic baths: from snowballs to polarons
Saajid Chowdhury, Jesús Pérez-Ríos
Solvation, the result of the complicated interplay between solvent-solute and solvent-internal interactions, is one of the most important chemical processes. Consequently, a comple…
