DESCRIPTION;ENCODING=QUOTED-PRINTABLE:ABSTRACT: Atomic spins moving in position-dependent magnetic fields are at the heart of many=0Aultracold atomic physics experiments. A mechanism known as a Majorana spin flip, causes loss from these magnetic traps. Though often avoided by various means, they play a larger role in a new form of hybrid trap - comprising a magnetic quadrupole superposed on an optical dipole potential. Previously, the spin-flip mechanism was modelled with a finite sized hole from which atoms are expelled from the trap. Instead, we numerically model the coupled spin and motional dynamics of an ensemble of atoms in a magnetic quadrupole field. Directly tracking the spin dynamics provides insight into the spin-flip mechanism and its effect on the velocity distribution of atoms remaining in the trap. The high computational demand of this simulation has prompted the parallelisation on Graphics Processing Units using NVIDIAs Compute Unified Device Architecture.
