The field of Bose-Einstein condensation (BEC) has recently seen some remarkable achievements. Researchers are now able to produce and manipulate BECs in magnetic microtraps formed by current carrying wires patterned onto a substrate (atom chip). This project extends work in this field to the investigation of physics at the quantum/classical boundary through the study of the dynamics of BECs on atom chips. By probing a nonlinear system with a BEC we will examine how the quantum mechanics affects classically chaotic dynamics. We will also examine the classically forbidden phenomena of dynamical tunnelling and localisation.
