SUMMARY:Physics Colloquium: Filomena Nunes
DESCRIPTION:Title: Nuclear Reactions for Astrophysics: A Theoretical Perspective \nAbstract: Advances in astrophysics require ever more precise knowledge from nuclear physics. Many of the reaction rates of interest for astrophysical simulations cannot be measured directly and instead are\nprobed with indirect nuclear reactions. A review of the various reaction techniques used to extract the information needed for stars\, including their explosions and collisions\, will be presented. I will then discuss theoretical developments over the last decade that have impacted the field of nuclear astrophysics and close with the many exciting open questions that reaction theory needs to tackle in the next decade. \nHost: Richard Longland

SUMMARY:Physics Colloquium: Bruce Vogelaar
DESCRIPTION:Title: Reducing Global Warming – An Urgent Quest to find an acceptable avenue for Nuclear Energy \nAbstract: Nuclear energy is globally recognized as a base-load capable energy source with essentially no carbon dioxide footprint. Light-water reactors have already been proven\, and advanced Gen 3+ and Gen 4 designs exist. But broader adoption is not just a technology issue – to unlock the true potential\, like in a tumbler lock\, requires all the pins to line up at the same time. One needs to also address long-lived waste\, the potential for major radiation release during accidents\, the large up-front costs\, and the potential for weapons proliferation. The latest designs often mitigate one\, or even two items\, but so far not all of them at once – which is what is really needed. \nBy merging high-energy physics accelerators and nuclear engineering\, an avenue to remove these barriers all at the same time is emerging. I will review the drivers behind the global dismay with existing nuclear energy to date\, and how a re-envisioned accelerator-driven system changes the picture – with designs being developed by several small companies outside of mainstream nuclear engineering\, and helped along by physicists! \nFLYER \nHost: Albert Young

SUMMARY:Physics Colloquium: Shimon Kolkowitz
DESCRIPTION:Title: A Brief History of Time (keeping): Metrology\, searches for new Physics\, and Tests of Relativity with Optical Lattice Clocks \nAbstract: Optical Lattice Clocks (OLCs) are now the most stable and accurate timekeepers in the world\, with fractional uncertainties equivalent to neither losing nor gaining a second over the entire age of the universe. This unprecedented level of metrological precision offers sensitivity to new physical phenomena\, opening the door to exciting and unusual applications. This talk will provide an introduction to how and why time is measured\, with an emphasis on OLCs and their applications. I will discuss recent progress on pushing OLCs to even greater levels of precision\, as well as prospects for future improvement. \nFinally\, I will give a brief overview of emerging applications of OLCs\, including research taking place at UW-Madison into using optical clocks for gravitational wave detection\, tests of general relativity\, and searches for physics beyond the Standard Model\, including recent progress we have made towards measuring the gravitational redshift at the centimeter scale.\n \nHost: Matt Green \n

SUMMARY:Physics Colloquium: Chandralekha Singh
DESCRIPTION:Title: Facilitating Thinking and Learning In and Beyond the Physics Classrooms \nAbstract: I will discuss\, using my research in physics education\, how research can be used as a guide to develop curricula and pedagogies to reduce student difficulties. My research has focused on improving student understanding of introductory and advanced concepts\, for example\, in learning quantum mechanics.  We are developing research-based learning tools such as tutorials and peer instruction tools that actively engage students in the learning process.  I will discuss how we evaluate their effectiveness using a variety of methodologies. \nI will also discuss our research studies that provide guidelines for how to enhance physics by making it inclusive. \nHost: Karen Daniels

SUMMARY:Physics Colloquium: Alicia Aarnio
DESCRIPTION:Title: The Magnetic Fields of Young Stellar Objects: Making\, Breaking\, and Braking of Planets and Stars \n\nAbstract: In this talk\, I will present a few vignettes of star and planet formation in which the star’s magnetic field plays a pivotal role. Spectroscopic and interferometric observations of young stars present a rich and complex picture of circumstellar environments in the epoch of planet formation\, and\, together\, have the power to disentangle observational ambiguities. For young solar analogs\, we’ll explore the exo-weather environments protoplanets may experience. Across the range of solar- and intermediate-mass stars\, I’ll discuss the role of magnetic fields in the accretion process in star and planet formation. Lastly\, I’ll share ongoing work toward understanding intermediate-mass stellar magnetic fields where observations are plagued by likely flux cancelation\, demonstrating how combined data set-driven simulations can help push modeling limits.\n\nHost: Vladi Skokov
