SUMMARY:Speaker: Mariel Pettee (LBNL) - Title: Towards a Foundation Model for Fundamental Physics
DESCRIPTION:Research Progress Meeting \nDate: February 1\, 2024 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Mariel Pettee (LBNL) \nTitle: Towards a Foundation Model for Fundamental Physics \nAbstract: The launch of ChatGPT in November 2022 ignited an ongoing worldwide conversation about the possible impacts of Large Language Models (LLMs) on the way we work. There is little doubt that LLMs will significantly influence many people’s jobs: one prominent study estimated that about 20% of the US workforce could soon see about 50% of their daily tasks influenced by these models. As scientists\, however\, the changes in our workflows since the advent of this technology have been relatively minor. \nWill this still be the case in 10 years? Could an analogous paradigm shift arise from a foundation model trained on a large amount of scientific data\, transforming the way we conduct our research? If so\, what can we learn from the development of other foundation models\, including LLMs\, in their evolution from specialists to (quasi-)generalists? In this talk\, I will present some recent work representing very early potential steps towards a foundation model of fundamental physics as well as perspectives on how we should strive to shape such a model to reflect our highest priorities as scientists.\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Lindley Winslow (MIT) - Title: The Search for GUT-Scale Axions: Really Big Magnets and Quantum Sensing
DESCRIPTION:Research Progress Meeting \nDate: February 6\, 2024 \nTime: 4:00- 5:00 pm  \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Lindley Winslow (MIT) \nTitle: The Search for GUT-Scale Axions: Really Big Magnets and Quantum Sensing\n \nAbstract: \nThe particle nature of dark matter remains one of the great open questions in physics. There is a broad category of candidates whose mass is so light that they behave more as waves than as particles. The most well-known is the axion\, which has had a renaissance as a dark matter candidate as theoretical studies have improved our understanding of axion cosmology and advances in quantum sensing and cryogenics have opened new opportunities for detection. In this talk\, I will focus on the search for GUT-Scale axions\, the DMRadio Program and the results from the ABRACADABRA demonstrators. If time permits\, I will also discuss our other R&D efforts that span from searching for primordial black holes to coupling quantum dots to SNSPDs. \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: William Coulton (Cambridge) - Title: Novel cosmological tests with precision CMB measurements
DESCRIPTION:Research Progress Meeting \nDate: February 15\, 2024 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: William Coulton (Cambridge) \nTitle: Novel cosmological tests with precision CMB measurements \nAbstract: High resolution cosmic microwave background (CMB) experiments provide views of the Universe both at redshift ~1100\, when the primary CMB was produced\, as well as an integrated view of the Universe between then and now\, through CMB secondary anisotropies. In this talk\, I will show that CMB secondary anisotropies contain a wealth of cosmological information and are becoming leading cosmological probes. I will present recent measurements from the Atacama Cosmology Telescope collaboration that have mapped out several of these effects. I will then highlight some challenges for these measurements with upcoming CMB experiments\, and some unique opportunities\, such as tests of the fundamental properties of our Universe. \nJoin Zoom Meeting \nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Clara Verges (Harvard) - Title: A new era for cosmology with current and next-generation CMB experiments
DESCRIPTION:Research Progress Meeting \nDate: February 20\, 2024 \nTime: 4:00- 5:00 pm  \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Clara Verges (Harvard) \nTitle: A new era for cosmology with current and next-generation CMB experiments \nAbstract: \nCosmology has experienced a considerable surge in the past thirty years\, and is now well established as a precision science. While the standard cosmological model provides an effective description of the observed Universe\, many fundamental questions remain unresolved. From shedding light on the very first fractions of seconds after the Big Bang to looking for exotic physics\, the Cosmic Microwave Background continues to be a unique probe for fundamental physics. The next generation of CMB polarisation observatories\, embodied by CMB-Stage 4 for ground observations\, will explore this window into the Universe in an unprecedented way\, enabling breakthrough science. I will review how current experiments such as the BICEP/Keck telescopes pave the way for this next stage\, by developing efficient technologies and observing strategies\, and by sharpening constraints on theoretical models. I will then discuss the scientific and technological challenges that the CMB community must meet to ensure the success of future experiments. \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Brendan Crill (Jet Propulsion Laboratory) - Title: Sensitivity limits to cosmological constraints on early Universe physics: lessons from Planck for future measurements
DESCRIPTION:Research Progress Meeting \nDate: February 27\, 2024 \nTime: 4:00- 5:00 pm  \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Brendan Crill (Jet Propulsion Laboratory) \nTitle: Sensitivity limits to cosmological constraints on early Universe physics: lessons from Planck for future measurements \nAbstract: \nThe past several decades have seen enormous breakthroughs in the understanding of fundamental physics of the Universe through observations of the cosmic microwave background (CMB) and large scale structure.  A synergy of rapid advances in technology\, data analysis capabilities\, and theory has led to an abundance of measurements\, which in turn has seen the success of the Lambda-CDM model seeded by early-Universe inflation.  This theory explains observations very few free parameters has emerged at explaining the observed structure of the universe. \nFurther refinements to this model and further characterization of observables in the CMB are a high priority for a deeper understanding of the nature of the physics of inflation and the evolution of structure across cosmic time.  This will come about through measurements of non-Gaussianity\, lensing\, and the imprint of tensor modes in large-scale CMB polarization among other observables. \nTo achieve these refinements\, projects have focused on improvements in raw sensitivity via new and more powerful detectors arrays with vastly more elements. \nHowever\, the success of earlier measurements has only come about through understanding and correction of systematic errors\, understanding astrophysical foregrounds: more powerful instruments with better sensitivity are likely to uncover new challenges. \nHere I describe lessons learned from the Planck mission at handling unforeseen instrumental and observational challenges and discuss prospects for fulfilling the sensitivity promise offered by large-scale structure projects such as SPHEREx and future CMB measurements. \n\nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037
