CREATED:20220907T205904Z DESCRIPTION:Ultracold gases of neutral atoms are a leading quantum science platform. They are at the heart of super-accurate atomic clocks\, novel quantum processing architectures\, powerful quantum simulators\, precise quantum sensors\, and leading tests of fundamental physics. Nearly all th is work has focused on three types of atoms (alkalis\, alkaline earths\, and dipolar lanthanides)\, leaving the majority of the Periodic Table une xplored in the ultracold regime. Here I will present our realization of a n ultracold gas of a new type of atom\, namely Main Group III of the Peri odic Table\, which are also known as the "triel elements". These particle s have many capabilities that are only found in isolation in other atom\n types. For example\, triels have tunable two-body interactions\, numerous magnetic orderings\, interesting forms of many-body coupling\, and the a bility to be probed with the precision of an atomic clock. I will discuss how the combination of these capabilities together in a single system pr esents new opportunities\nfor quantum simulations of many-body systems.

CREATED:20220922T174929Z DESCRIPTION:Linkages\, networks of nearly rigid bars meeting at freely rot ating joints\, serve as a simple mathematical model underpinning a variet y of physical systems\, from molecules to disordered spring networks to o rigami. Recent advances in fabrication such as 3D printing has driven a r esurgence of interest in designing mechanical systems based on linkages t hat can serve as "mechanical metamaterials"\, materials whose properties can be controlled by cleverly designing their structure. Despite the math ematical aphorism "One can design a linkage which will sign your name!"\, suggesting that one could make a metamaterial do anything\, it turns out to be very hard to do in practice. I will discuss recent work in our gro up on understanding the mechanics of linkages\, origami\, and other mecha nisms from the point of view of designing and controlling "singularities\ ," places where the configuration space of a mechanism fail to be smooth - and where small changes of shape can lead to dramatic changes in behavi or. This sheds light on the surprising rigidity of very under-coordinated networks of springs and enables the design of mechanical gates and other logic devices.

CREATED:20221005T170830Z DESCRIPTION:Many important applications in biochemistry\, materials scienc e\, and catalysis sit squarely at the interface between quantum and stati stical mechanics: coherent evolution is interrupted by discrete events\, such as binding of a substrate\, isomerization\, or chemical exchange. Of ten these effects are detected by the changes they make to a molecular sp ectrum (rotational\, vibrational\, electronic\, or nuclear spin) and the theoretical treatment of the effects of exchange on spectra were original ly explored in detail in the late 1950's1\,2. We recently discovered that the theory for incorporating chemical exchange into quantum evolution wa s incorrect\, having made false statistical assumptions about the dynamic s. We completely rebuilt this theoretical framework3\,4\, which led to th e discovery of new physical effects as well as significant computational improvements for no additional cost\; more recently\, we have extended th is to correct the Lindblad formulation of exchange usually used in proble ms such as ion trap dynamics4. I will focus on one important application\ , understanding a relatively new technique for producing very large nucle ar magnetization called SABRE (Signal Amplification By Reversible Exchang e)\, which can generate on the order of 10\,000-fold enhancement of magne tic resonance signals in under a minute. SABRE uses para-hydrogen\, perha ps the only "quantum reagent" stable at room temperature\, to create larg e magnetization in other molecules in solution. It uses bizarre field co nditions very different from "normal" magnetic resonance at many Tesla (t ypically\, <1 mT\, which is about 1% of the Earth's field) and thus the t heoretical aspects were underexplored. Combining theoretical and experime ntal efforts for this problem has permitted significant improvements in t he both the scope5\,6 and performance7\,8 of this method.\n\n1 Kaplan\, J .\, J. Chem.

Math is a deeply human enterprise that fulfills basic human long ings\, such as for beauty and exploration and truth\, and when properly e ngaged\, it builds virtues like persistence\, creativity\, and a competen ce to solve problems you've never seen before. Reframing math in this way ---around virtues---offers a more attractive way to welcome people to see math as an intrinsic part of life\, and to teach it in a more equitable\ , inclusive way. An incarcerated man---now my friend---has helped me see this more clearly than ever before.\n\nThis event is sponsored by Mathema tics and Duke Faculty Advancement.

It juxtaposes the stories of two women tr ying to find their place in a white male-dominated academic world. The fi rst is of historical Russian mathematician Sofia Kovalevskaya\, who was l auded as a pioneer for women in science but only after years of struggle for recognition. Her life's journey is told through music and movement\, in both Russian and English. The second is of a fictional Asian-American woman\, known only as "Professor"\, trying to cope with the prejudice sh e faces in the present. As she teaches an introductory real analysis clas s\, she uses mathematical concepts to draw parallels to the race and gend er conflicts she encounters in society today.\n\nThe Duke Math DEI Commit tee will host a special tea following her performance at 4pm in the Math Lounge (Physics 101).

We can use neutrinos to probe the properties of nuclei\, and use nuclei as targets for detecting neutrinos. In this seminar\, I wi ll present my past research on COHERENT and nEXO\, and describe my experi mental research program measuring nuclear matrix elements important for n eutrinoless double beta decay of germanium-76\, searching for Dark Matter in naturally occurring minerals with the PALEOCCENE collaboration\, and developing new technology to detect some of the lowest energy neutrinos p roduced on Earth. I'll describe how the resources available at TUNL can h elp characterize backgrounds for these experiments and provide supporting measurements to enable this program.

Understanding nuclear structure includi ng resonances and the properties of bulk nuclear matter is necessary for constraining the stellar behaviour. In this talk\, I will discuss some of my research focusing on how nuclear structure studies can be used to inf orm stellar behaviour with particular focus on how experiments can be use d to constrain elemental abundances and the properties of neutron stars.

Th e most illuminating of these data has been for the neutron-rich nuclei ar ound N = 20 and 28. A smooth decrease in the separation of the 2p3/2-2p1/ 2 spin-orbit splittings is observed as they approach zero binding\, which is at odds with the well-accepted scaling\, with mass\, of measured spin -orbit splittings across the chart of nuclides for well-bound states as e stablished by Mairle [Phys. Lett. B 304\, 39 (1993)]. In studying the con trast between experimental data\, the mean-field descriptions\, and the t rends established by Mairle for both well-bound and weakly bound systems across the nuclear chart\, with a focus on neutron spin-orbit partners\, a seemingly universal behavior emerges that could prove predictive. Many of the regions explored have connections to other prominent topics in nuc lear physics\, such as r-process nucleosynthesis\, where the ordering of single-particle energies near threshold in weakly bound systems plays a r ole in reaction rates. Throughout\, I will highlight one of the principal techniques used to extract such data: the solenoidal spectrometer techni que\, now used at ATLAS\, CERN\, and FRIB. This material is based upon wo rk supported by the U.S. Department of Energy\, Office of Science\, Offic e of Nuclear Physics\, under Contract Number DE-AC02-06CH11357.
