SUMMARY:Workshop / Seminar:Special HEP-Astro Seminar | Search for Dark Matter Interactions at High Recoil Energy with the LUX-ZEPLIN Experiment
DESCRIPTION:The LUX-ZEPLIN (LZ) experiment is a dual-phase xenon time projection chamber designed to search for dark matter interactions with unprecedented sensitivity. While conventional WIMP searches focus primarily on low-energy nuclear recoils\, a broader class of dark matter  models can produce significant signals at much higher recoil energies. In a new search using 2.84 tonne-years of LZ exposure\, we extend the nuclear-recoil energy window to approximately 270 keV to probe momentum- and velocity-dependent interactions described by non-relativistic effective field theory\, as well as inelastic dark matter models. The search observes one event in a region of low expected background\, consistent with a 248 +/- 23 (stat) +/- 23 (sys) keVnr nuclear recoil. I will describe the motivation\, methodology\, and results of this extended-energy search\, including the investigation of the high-energy event and possible background interpretations. I will also highlight work carried out at the University of Michigan that helped enable the extension to high recoil energies\, particularly the calibration and detector-response modeling of electronic and nuclear recoils\, together with studies of backgrounds relevant to the expanded search region.

SUMMARY:Lecture / Discussion:MIPSE Seminar | Xcimer’s Approach to Inertial Fusion Energy
DESCRIPTION:Abstract: \nXcimer Energy Corporation is developing a new generation of large‑scale\, high‑efficiency excimer laser systems designed to enable practical inertial fusion energy. This talk will outline the physics and engineering foundations of high‑energy KrF laser architectures and their advantages for coupling energy to direct‑drive fusion targets. This presentation will describe Xcimer’s integrated roadmap for de‑risking and scaling the technology. These strategies include the Phoenix program to demonstrate and validate gas optics performance\; Anvil\, Xcimer’s first dedicated target‑shooter facility to derisk two beam implosion\; and Vulcan\, a 4‑MJ‑class laser system intended to demonstrate fusion breakeven. The seminar will also introduce Athena\, a conceptual fusion pilot plant featuring a liquid first wall designed for a 40‑year lifetime and compatible with high‑repetition‑rate operation. Together\, these developments form a coherent pathway towards high‑gain direct‑drive targets and commercially relevant fusion energy systems. The talk will highlight the system‑level considerations that motivate excimer technology\, the target‑design implications of higher available laser energy\, and the engineering concessions required for a viable fusion power plant.\n\nAbout the Speaker: \nAlison Christopherson is the Head of Target Design at Xcimer Energy Corp. where she leads the development of high‑gain direct‑drive targets for next‑generation excimer‑laser–driven inertial fusion energy systems. She earned her B.S. in Nuclear Engineering from the University of Michigan and her Ph.D. from the University of Rochester\, specializing in direct‑drive inertial confinement fusion. Her doctoral work advanced understanding of alpha particle heating and ignition\, earning her the Rosenbluth Award for excellence in plasma physics. She went on to serve as a staff scientist in the Inertial Confinement Fusion program at Lawrence Livermore National Laboratory during the period when ignition was first achieved. Her experience at LLNL reinforced a key conclusion: solid‑state laser architectures face fundamental scaling limits for the energy levels required to produce robust\, high‑gain targets and to accommodate the engineering concessions of a fusion power plant. Motivated by the promise of gas‑optics–based excimer technology\, she joined Xcimer to lead its target design program and shape the physics basis for the company’s fusion roadmap.\n\nThe seminar will be conducted in person\, with livestream on Zoom.

SUMMARY:Lecture / Discussion:Democracy Against Workers?
DESCRIPTION:Webinar Link: https://myumi.ch/ww7q9\n\nCanonical models of democracy expect working-class people to be the main beneficiaries -- even the natural beneficiaries -- of democratization. Yet not all democratic systems deliver economic gains to average citizens. Even after they gain the right to vote\, very rarely do they become candidates for office and get to serve as the people's representatives. When is \"democracy against workers\" and how might we make it work better for working people? In this Democracy Week roundtable\, Nick Carnes\, Adam Dean\, and Noam Lupu discuss their book projects on these themes\, with Ann Heffernan serving as respondent.\n\nIf there is anything we can do to make this event accessible to you\, please contact us at emergingdemocracies@umich.edu. Please be aware that advance notice is necessary as some accommodations may require more time for the university to arrange.
