This award is funded in whole or in part under the American Rescue Plan Act of 2021 (Public Law 117-2). Quantum simulation is the practice of experimentally modelling a complex physical system using an analogous quantum system, where the underlying fundamental nature of the system is preserved. Ultracold quantum gas experiments provide an exceptionally powerful and tunable platform for direct investigations of a wide variety of physical phenomena, including non-equilibrium quantum dynamics, few-body physics, atom interferometry, and condensed matter physics. The development and creation of an ultracold quantum gas experiment presents many complex challenges for student researchers to overcome, requiring one to attain a variety of technical skills and knowledge, including electronic design and testing, ultra-high vacuum technologies, optomechanical design, electromagnetic modeling and control, and computational integration with automation programming. A table-top system with these high-performance technologies is an excellent training ground for undergraduate researchers in physics and engineering. Through small, well-defined projects, undergraduate researchers can develop highly applicable research skills sought after in the quantum information science and technology industry and in advanced research settings. This project will establish the infrastructure for rigorous, accessible, hands-on quantum research at a primarily undergraduate institution.The research activities proposed here will build the foundations of a platform that will elucidate phase-separation dynamics and driven turbulent behavior in dilute-gas superfluids. Important questions that will be addressed in this project include: (1) How does phase separation behave in a channel BEC with both miscible and immiscible components? (2) How does quantum turbulence vary as the system interactions are quenched from being weakly miscible to immiscible? (3) Can hydrodynamic instabilities form between two spin states in a single isotopic BEC? These studies have applications beyond ultracold atomic physics, from classical fluid flow and nonlinear optical systems to supernovae and neutron stars. The Principal Investigator’s student mentorship plan revolves around building and strengthening a student’s physics identity. This includes developing positive relationships and technical lab skills as well as participating in the dissemination of research at conferences. These activities will increase the recruitment and retention of historically underrepresented students in physics and engineering and will provide challenging research experiences in quantum information science and technology.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项的全部或部分资金来自《2021年美国救援计划法案》(公法117-2)。量子模拟是使用类似的量子系统对复杂的物理系统进行实验建模的实践，其中保留了系统的潜在基本性质。超冷量子气体实验为直接研究各种物理现象提供了一个极其强大和可调的平台，包括非平衡量子动力学、少体物理、原子干涉计量学和凝聚态物理。开发和创造超冷量子气体实验给学生研究人员提出了许多复杂的挑战，需要克服这些挑战，需要掌握各种技术技能和知识，包括电子设计和测试、超高真空技术、光学机械设计、电磁建模和控制，以及与自动化编程的计算集成。具有这些高性能技术的桌面系统是物理和工程专业本科生研究人员的极好培训场所。通过小型的、完善的defiNed项目，本科生研究人员可以开发出在量子信息科学和技术行业以及高级研究环境中受到追捧的高度适用的研究技能。这个项目将在一个以本科生为主的机构为严格的、可访问的、动手的量子研究建立基础设施。这里提出的研究活动将建立一个平台的基础，该平台将阐明相分离动力学和稀薄气体超流体中的驱动湍流行为。本项目要解决的重要问题包括：(1)在含有可混溶和不可混溶成分的沟道BEC中，相分离是如何表现的？(2)当系统相互作用从弱可混溶到不混溶时，量子湍流是如何变化的？(3)在单个同位素BEC中，两个自旋态之间是否会形成流体动力学不稳定性？这些研究的应用范围超出了超冷原子物理学，从经典的流体流动和非线性光学系统到超新星和中子星。首席调查员的学生导师计划围绕建立和加强学生的物理认同感。这包括发展积极的关系和技术实验室技能，以及参与在会议上传播研究成果。这些活动将增加物理和工程专业历史上代表性不足的学生的招生和留住，并将提供具有挑战性的量子信息科学和技术研究经验。该奖项反映了NSF的法定使命，并通过使用基金会的智力优势和更广泛的影响审查标准进行评估，被认为值得支持。
