| Nuclear CP Violation Searches with Neutral Molecules in QuESTLab at FRIB |
| Speaker: | Alexander Frenett (Michigan State University) |
| Abstract: | Radioactive molecules provide a distinct set of advantages in searches for CP-violation. However, the same molecular properties that deliver these benefits also significantly complicate quantum control and readout. In this talk, we discuss how QuEST Lab, a new project at the Facility for Rare Isotope Beams (FRIB), applies expertise in traditional AMO techniques and develops novel methods to wrangle neutral radioactive molecules in service of nuclear CP violation searches. We first present a cryogenic buffer gas beam (CBGB) experiment on 227ThO, capable of competing with Schiff-moment limits in the near-term, thanks to direct experience with, and plentiful literature on, ThO structure. We describe development of a magnetic centrifuge decelerator capable of slowing beams of almost arbitrary atoms and molecules. Though of obvious interest to CP-violation experiments, we also discuss how the |

| Machine learning for gravitational-wave inference at scale |
| Speaker: | Ippocratis Saltas (Czech Academy of Sciences) |
| Abstract: | Gravitational-wave astronomy promises a major advance in fundamental physics, but it also poses severe computational challenges. Signals are weak and buried in noise, detector noise is non-stationary, and standard Bayesian inference can require days to weeks per event. With next-generation detectors, inference must scale to longer signals, higher event rates, and real-time analysis, making traditional approaches increasingly prohibitive. In this talk, I will briefly introduce the basics of gravitational waves and outline how machine learning can play an enabling role by dramatically reducing computational cost. I will then review key challenges and discuss recent progress toward models with transfer-learning capabilities that remain reliable across detectors and waveform modelling, with relevance to emerging foundation-model efforts in physics. |
