This experimental research program explores new territories in nonlinear optics and low temperature physics. The apparatus has been specifically developed to implement a double light roadblock, an extension of ultra-slow light techniques, to generate collisions between nonlinear excitations in the quantum fluids. The plan is to apply the double light roadblock setup, and implement a high-resolution imaging system to image the dynamics of condensates in-situ in order to maintain better control of their density, with the option of imaging their dynamical sequences non-destructively. The PI will study collisions between these nonlinear excitations and hopes to map out a whole hierarchy of increasingly complex collisional products. The broader impact of the program involves creating an interactive, chat-room-type website to more effectively reach a larger audience.

该实验研究计划探索非线性光学和低温物理学的新领域。该装置是专门开发的，以实现双光路障，超慢光技术的扩展，以产生量子流体中的非线性激发之间的碰撞。该计划是应用双光路障设置，并实施高分辨率成像系统，以现场成像凝析物的动态，以保持更好地控制其密度，并选择非破坏性地成像其动态序列。PI将研究这些非线性激发之间的碰撞，并希望绘制出越来越复杂的碰撞产物的整个层次。该计划的更广泛影响包括创建一个互动的聊天室类型的网站，以更有效地接触更多的受众。
