The primary objective of this project is to explore the physics of heteronuclear models: coupled atom-molecule systems where heteronuclear or polar molecules are formed from atoms of distinct species via interspecies Feshbach resonance or photoassociation. The technique of the stimulated Raman adiabatic passage will be generalized to multi-level atom-molecule systems for the purpose of an efficient generation of polar molecules. The same technique is also applied to create a large angle atom-molecule beam splitter, which serves as the building block for an atom-molecule interferometer, capable of measuring changes that are phase sensitive not only to atomic but also to molecular beams. Electromagnetically induced transparency is studied as an tool for detecting exotic phases in two-states fermionic models, taking advantage of the exceptionally high spatial and frequency resolving powers of modern lasers. Phase separation in which different phases repel each other into separate spatial regions is studied with a new attitude, in which phase separation is considered as offering new opportunities for building quantum devices of practical importance. A separated quantum phase inside an optical cavity is studied not only as a fundamental nonlinear system for the exploration of cavity quantum electrodynamics but also as a tool for precision measurement of quantum phenomena.This project aims to provide more competitive research programs to students at Rowan, a predominantly undergraduate public institution. Students are provided with chances to collaborate with the PI's former students (currently at other graduate institutions), and visiting Ph. D students or scholars from collaborating institutions, all of which represent opportunities that are traditionally only accessible to students at large research universities. The goal is to equip Rowan students with the research experience and the skills that will enable them to compete with those from nationally-recognized universities in future graduate studies or other scientific careers. This project also aims to motivate the PI to further his effort in integrating research into teaching while advancing discovery and understanding through his active research program. The goal is to provide undergraduate students with a more direct path to advanced research topics in atomic physics and quantum optics, while at the same time to lay groundwork that enables the students to expand comfortably into any advanced areas of study in the future.

该项目的主要目标是探索异质结模型的物理学：耦合原子-分子系统，其中异质结或极性分子通过种间Feshbach共振或光缔合由不同物种的原子形成。 受激拉曼绝热通道技术将被推广到多能级原子-分子系统，以有效地产生极性分子。 同样的技术也被应用于创建一个大角度的原子-分子分束器，它作为原子-分子干涉仪的构建模块，能够测量不仅对原子束而且对分子束相敏的变化。利用现代激光器极高的空间和频率分辨能力，研究了电磁感应透明作为探测两态费米子模型中奇异相的工具。 以一种新的态度研究了相分离，其中不同的相相互排斥到单独的空间区域，其中相分离被认为是为构建具有实际重要性的量子器件提供了新的机会。 光腔中分离的量子相位不仅作为探索腔量子电动力学的基本非线性系统，而且作为量子现象的精确测量工具进行研究。本项目旨在为以本科为主的公立机构Rowan的学生提供更具竞争力的研究项目。 学生有机会与PI的前学生（目前在其他研究生院）合作，并访问博士生或合作机构的学者，所有这些都代表了传统上只有大型研究型大学的学生才能获得的机会。我们的目标是使罗文学生具备研究经验和技能，使他们能够在未来的研究生学习或其他科学职业中与国家认可的大学竞争。 该项目还旨在激励PI进一步努力将研究融入教学，同时通过积极的研究计划推进发现和理解。 我们的目标是为本科生提供一个更直接的途径，以先进的研究课题在原子物理学和量子光学，而在同一时间奠定基础，使学生能够舒适地扩展到任何先进的研究领域在未来。
