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.Read moreRead less
