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.

玻色-爱因斯坦凝聚（BEC）领域最近取得了一些令人瞩目的成就。 研究人员现在能够生产和 在磁性微陷阱中操纵 BEC，该微陷阱由基板（原子芯片）上图案化的载流线形成。 该项目通过研究原子芯片上 BEC 的动力学，将该领域的工作扩展到量子/经典边界的物理研究。通过使用 BEC 探测非线性系统，我们将研究量子力学如何影响经典混沌动力学。 我们还将研究动态隧道效应和局部化的经典禁止现象。
