SUMMARY:Speaker: Paul Stankus (Brookhaven National Laboratory) - Title: Quantum-Enhanced Astronomy For Both Fun and Profit
DESCRIPTION:Research Progress Meeting \nDate: September 7\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Paul Stankus (Brookhaven National Laboratory) \nTitle: Quantum-Enhanced Astronomy for Both Fun and Profit\n \nAbstract: Quantum devices are finding their way to improving many kinds of technologies\, at an increasing pace. We will review ideas for how astronomical measurements\, particularly using interferometers\, can be improved — in some cases greatly so — through the new application of quantum devices such as quantum memories\, single-photon sources\, quantum repeaters\, quantum teleportation\, and more. Then we will take a look at active experimental work in this area and prospects for near-future instruments. Lastly\, we will discuss interesting astrophysical observations that could be enabled by quantum enhancement\, including distance ladder measurements\, exoplanet spectra\, and even low-frequency gravitational waves\, among others. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Uros Seljak (LBNL) - Title: AI for Physics\, Physics for AI
DESCRIPTION:Research Progress Meeting \nDate: September 14\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Uros Seljak (LBNL) \nTitle: AI for Physics\, Physics for AI\n \nAbstract: Artificial Intelligence (Machine Learning) is revolutionizing many aspects of our life\, but its success stories in physics and astronomy are rare and limited to a few subfields only. I will argue that this is because physics applications require development of physics specific AI methods\, rather than using off the shelf methods from the AI community. A few examples of physics specific nature of the data are large dimensionality of the data\, stochastic nature of the data\, and symmetries. I will argue that learning the data structures first using generative learning approaches such as Normalizing Flows enables not only better learning\, but also provides additional information on robustness\, such as anomaly detection. These methods applied to cosmology data show the promise of up to an order of magnitude improvement relative to traditional methods. Physics ideas have also influenced the development of AI\, and many of these have been based on stochastic processes and sampling. I will discuss recently developed MicroCanonical Hamiltonian and Langevin Monte Carlo\, which are a new class of sampling methods that outperform previous state of the art such as Hamiltonian Monte Carlo\, in some cases by orders of magnitude. These new sampling methods will in turn enable solutions of physics problems that were not possible before\, in a wide range of fields from cosmology to lattice QCD. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Naoko Kurahashi Neilson (Drexel) - Title: Neutrino Astronomy\, From Dream to Reality
DESCRIPTION:Research Progress Meeting \nDate: September 21\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Naoko Kurahashi Neilson (Drexel) \nTitle: Neutrino Astronomy\, From Dream to Reality\n \nAbstract: The Universe has been studied using light since the dawn of astronomy\, when starlight captured the human eye. The IceCube Neutrino Observatory\, located at the geographic South Pole\, observes the Universe in a different and unique way: in high-energy neutrinos. IceCube’s discovery in 2013 of a diffuse celestial neutrino radiation started an era of neutrino astronomy. Searches for astronomical sources responsible for creating these neutrinos have covered broad source types while combating background event rates that are 6 orders of magnitude higher. This year\, the first observation of our own Milky Way galaxy in neutrinos was announced in June. This talk will cover how this observation was made\, other milestone observations by IceCube\, and the state of neutrino astronomy. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239

SUMMARY:Speaker: Jia Liu (Kavli IPMU University of Tokyo) - Title: Neutrinos\, baryons\, cosmic web\, and COVID19
DESCRIPTION:Research Progress Meeting \nDate: September 26\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Jia Liu (Kavli IPMU University of Tokyo) \nTitle: Neutrinos\, baryons\, cosmic web\, and COVID19\n \nAbstract: This won’t be your usual seminar\, but rather a report back since I left Berkeley two years ago. Despite barely having made it to campus or the lab due to mat leave + COVID\, I managed to work with many Berkeley people on various projects\, almost all of which happened serendipitously. I will touch upon the topics mentioned in the title. I will also discuss prospects for Stage IV cosmology\, in terms of joint simulations and analysis with CMB and LSS surveys. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/95679892182?pwd=RU5xU2dDRFNabnR1U3pQMklkYWFIdz09 \nMeeting ID: 956 7989 2182 \nPasscode: 169037

SUMMARY:Speaker: Chris Polly (Fermilab) - Title: New results from the Fermilab Muon g-2 Experiment
DESCRIPTION:Research Progress Meeting \nDate: September 28\, 2023 \nTime: 4:00- 5:00 pm \nLocation: Sessler Conference Room- 50A-5132 [In-Person and HYBRID]  \nSpeaker: Chris Polly (Fermilab) \nTitle: New results from the Fermilab Muon g-2 Experiment\n \nAbstract: The Muon g-2 collaboration recently published their latest results for the determination of the anomalous magnetic moment of the muon. This result is a factor of two more precise than prior experiments and is in good agreement with past determinations. A description of the experimental result\, future plans\, and a discussion of the theory will be presented. \nJoin Zoom Meeting\nhttps://lbnl.zoom.us/j/98854322464?pwd=K2tKUm1VZjRlV1J5RHE3cXdHQzRxdz09\n\nMeeting ID: 988 5432 2464\n\nPasscode: 142239
