  • Weak Supervision for RFI Mitigation in 21-cm Cosmology

    Seminar
    Room 112 (Watanabe Hall)
    Journal Club

    Speakers: Dr Shawn Dubey Detecting the redshifted 21-cm signal from the early universe requires separating an extremely faint cosmological signal from bright foreground emission and terrestrial radio-frequency interference (RFI), but flagging RFI is a big challenge. I will describe our use of weak supervision, a method that combines multiple imperfect flaggers to construct training labels ... Read more

  • Physics from quantum information

    Seminar
    Room 112 (Watanabe Hall)
    Journal Club

    Speakers: Prof. Dejan Stojkovic (SUNY, Buffalo) We formulated an alternative to quantum mechanics, whose basic starting point is pure information represented by binary sequences, without any reference to space, time, and matter. Defining correlations between the sequences, we derived highly non-trivial QM results: rules of angular momentum addition, quantum harmonic oscillator, Clebsch-Gordan coefficients, and Wigner’s d-matrix formula. ...

  • A Systematic Approach to Axion Production at Finite Density

    Seminar
    Room 112 (Watanabe Hall)
    Journal Club

    Speakers: Michael Stadbauer (Max Planck Institute for Physics/Technical University of Munich (TUM)) As an elegant solution to the strong CP problem and promising dark matter candidate, the QCD axion is one of the best motivated particles beyond the SM. On the phenomenological side, it is extremely predictive as all its couplings to SM particles, as ... Read more

  • Rethinking Math Readiness for First-Year Physics and Engineering

    Colloquia
    Room 112 (Watanabe Hall)
    Colloquium

    Speakers: Joel Walker (Sam Houston State University) I’ll be describing an intervention targeting math readiness for incoming physics and pre-engineering students, which has been co-developed with faculty colleague James Dent at Sam Houston State.  Our “Physics Bootcamp” course teaches the mathematical methods required for first-year physics and engineering, from the perspective favored by physicists. Motivated ... Read more

  • Closing in on Sub-GeV Dark Matter

    Room 112 (Watanabe Hall)
    Journal Club

    Speakers: Rebecca Leane (SLAC and KIPAC) Sub-GeV dark matter is a well-motivated possibility. However, its feeble interactions make it hard to detect, often falling below experimental thresholds, requiring new detection ideas. In this talk I will describe two complementary, data-driven strategies to close in on light dark matter. First, I will show how large neutrino ... Read more

  • Learning Quantum Systems through Physics-Inspired Artificial Intelligence

    Colloquia
    Room 112 (Watanabe Hall)
    Colloquium

    Speakers: Bo-Han Wu (UHM) Quantum technologies, including sensing, communication, and computing, are reshaping modern science by exploiting nonclassical resources such as coherence, entanglement, and squeezing. Despite significant progress, their advancement remains limited by the lack of system-level co-optimization that connects physical hardware and algorithmic design. Conventionally, quantum hardware and information processing have been developed independently, ... Read more

  • X-ray Free-Electron Lasers: Past, Present and Future

    Room 112 (Watanabe Hall)
    Colloquium

    Speakers: Zhirong Huang (SLAC National Accelerator Laboratory) The world’s first hard X-ray Free Electron Laser (FEL), Linac Coherent Light Source (LCLS), started its operation 16 years ago and ushered in a new era of ultrafast X-ray science. More recently, the world’s first continuous-wave X-ray Free Electron Laser (FEL), LCLS-II, began lasing and user operation. In ... Read more

  • Cortical decision-making with non-equilibrium steady state activity

    Room 112 (Watanabe Hall)
    Colloquium

    Speakers: Jochen Braun (Otto-von-Guericke University) Abstract: Sensory perception continually searches for interpretable structure in a dynamic world. How does the sensory cortex of primates make these perceptual decisions rapidly and reliably? In contrast to current theories that invoke equilibrium dynamics and assume stable decision states, and predict no post-choice events, I propose that the basic ... Read more

  • On spikes and sound: debating the physical nature of action potentials

    Room 112 (Watanabe Hall)
    Colloquium

    Speakers: Matan Mussel (University of Haifa, Israel) Abstract: Excitable cells generate a characteristic transient change in transmembrane potential that propagates along the cell membrane in response to suitable stimuli. These signals are called action potentials (APs), and are principally associated with behavioral activities of many organisms. Thus, an understanding of the mechanism of APs, as ... Read more

  • Publish, Don’t Perish! “Writing for Academic Publication” Workshop

    Room 112 (Watanabe Hall)
    Colloquium

    Speakers: Issac Wang, Siobhan K. H. Brimhali Come all! This highly interactive workshop, presented in coordination with the Writing Center, is designed to enhance some of the foundational tools needed to successfully present your research to an academic journal audience. Some of the topics that will be covered are "structuring a paper for journals in ... Read more

  • Application of FPGA devices in experimental high-energy physics

    Room 112 (Watanabe Hall)
    Colloquium

    Speakers: Yun-Tsung Lai (KEK) Abstract: In the high-energy experiments, especially for those with high luminosity collider, the data acquisition system is designed to be capable of handling large event rate and data size. Electronics devices with Application Specific Integrated Circuit (ASIC) and Field-Programmable-Gate-Array (FPGA) are essential to perform real-time processing on the data from particle ... Read more
