A treecode algorithm for simulating electron dynamics in a Penning-Malmberg trap

A treecode algorithm is presented for computing the electrostatic potential and electric field in a system of charged particles. The algorithm is grid-free and with N particles it reduces the operation count to O(N logN), as opposed to O(N2) which is required for direct summation of pairwise interactions. The key idea is to replace the particle
