Numerical modeling of collisional dynamics of Sr in an optical dipole trap

Abstract

We describe a model of inelastic and elastic collisional dynamics of atoms in an optical dipole trap that utilizes numerical evaluation of statistical mechanical quantities and numerical solution of equations for the evolution of number and temperature of trapped atoms. It can be used for traps that possess little spatial symmetry and when the ratio of trap depth to sample temperature is relatively small. We compare simulation results with experiments on ${}^{88}$Sr and ${}^{84}$Sr, which have well-characterized collisional properties.
