Abstract: Breathomics aims to address the current unmet clinical needs by utilizing exhaled breath contents for non-invasive and real-time medical diagnostics. We demonstrate a frequency comb breathalyzer powered by machine learning for detecting COVID-19, finding 85 % accuracy among a 170-subject cohort. To enhance diagnostic power, we introduce Modulated Ringdown Comb Interferometry, a new technique enabling the quantification of “odor” of arbitrarily complex and unknown contents at new record sensing performance and requiring only simple instruments.

Abstract: In the last several years, the combination of resolved event horizon scale images and large-scale computational models has led to new insights into black hole accretion. The main implication is that magnetic fields near the event horizon can become dynamically important, and I'll show that such a scenario provides a natural explanation for the high energy flares from our Galactic center black hole.

Abstract: Galaxies are intimately connected to the environments they live in. The haloes around them contain the gas reservoir from which the galaxies grow, while galactic outflows heat and enrich this circumgalactic medium (CGM). The elemental abundances of present-day stars are, in part, set by these cosmic gas flows. Using zoom-in cosmological simulations of galaxies, I will discuss the physical and observable properties of gas and stars in and around galaxies.

Symposium Highlights

The JILA Association of Graduate Students (JAGS) is excited to announce the next session of the JILA Graduate Student Seminar Series! Please join us next Thursday, June 5th, at 12:30 in the JILA Auditorium, with the talks beginning at 12:45.

The talks for this session are:

Student voice in quantum education - Kristin Oliver, Lewandowski PER Group

Engineering Collective Decoherence-Free Subspaces - Lyryl Vaecairn, Holland Group

Please come by and explore the research going on at JILA! There will also be lunch provided.

Nonequilibrium quantum systems exhibit phenomena not seen in equilibrium but are also less well understood. To study these systems, quantum simulators hold much promise due to their broad tunability and access to measurement observables. In this defense, I present experiments engineering nonequilibrium quantum phases of matter using many strontium atoms in a high-finesse optical cavity. Observations include a first experimental realization of three dynamical phases in quenched BCS superconductors and insights into many-body gap protection in fermionic superfluids.
