In the last decade, quantum gas microscopy has emerged as a powerful technique to probe and
manipulate quantum many-body systems at the single-atom level. So far, however, it has only been used for the study of lattice and spin chain physics, prominently to explore the Hubbard model and its generalizations. In this talk, I will present our recent efforts to extend quantum gas microscopy to the study of fermionic many-body systems in continuous space and characterize them at previously inaccessible levels of resolution and control.

Join an evening of fun with your family and colleagues before the academic year begins! The event includes carnival games and inflatables, free food, music, wellness resources, and free backpacks with school supplies (limited). 

Abstract: Science faces an accessibility challenge. Although information/knowledge is fast becoming available to everyone around the world, the experience of science is significantly limited. One approach to solving this challenge is to democratize access to scientific tools. We believe this can be achieved via “Frugal science”; a philosophy that inspires design, development and deployment of ultra-affordable yet powerful scientific tools for the masses.

Reception to follow talk in the h-Bar.

Abstract: We observed a narrow (~100 kHz) 229Th nuclear clock transition in Th-doped CaF2 crystals using a VUV frequency comb. The VUV comb directly links the 229Th nuclear transition frequency to the JILA Sr optical clock, enabling determination of the absolute 229Th clock frequency. These results represent a milestone in building solid-state nuclear clocks for precision measurements and fundamental physics.

Abstract: Particle, nuclear, and astrophysics experiments are producing massive amounts of data to answer fundamental questions about the basic constituents of our universe.  While researchers in these areas have been using advanced data science tools for decades, modern machine learning has introduced a paradigm shift whereby data can be directly analyzed holistically without first compressing it into a more manageable and human understandable format.  How will the machines help us explore the unknown?  Can they be trusted to give us the right answers?

Abstract: 

We present the development and uncertainty evaluation of a transportable ytterbium optical lattice clock, achieving a total systematic uncertainty level of 3.7 ×10^-18. We also report a field test of the clock after transporting it to Washington DC, demonstrating the clock’s reliability and readiness to contribute to scientific efforts such as the redefinition of the SI second and frequency-based measurements of Earth’s geopotential.

Join us for a presentation about the recent STROBE NSF Site Review that took place in January 2024. From an institute perspective, this presentation will cover the entire timeline of the review, the types of inquiries and CU's response to the review team, and best practices and tips for working with reviewers. Discussion and question/answer will follow the presentation. All are welcome!

Abstract: Spin glasses—large-scale networks of spins with deeply frustrated interactions—are canonical examples of complex matter. Although much about their structure remains uncertain, they inform the description of a wide array of complex phenomena, ranging from magnetic ordering in metals with impurities to aspects of evolution, protein folding, climate models, and combinatorial optimization. Indeed, spin glass theory forms a mathematical basis for neuromorphic computing and brain modeling.
