Marcelo Rubio ---------- Title: Challenges in relativistic viscous hydrodynamics Abstract: I will discuss recent progress on the development of relativistic theories for the description of viscous fluid systems, and their implications in numerical relativity. After briefly reviewing previous attempts at dissipative fluid theories in fully relativistic frameworks, I will elaborate on some recent interesting works and, […]
Title: ML-assisted statistical inference in particle physics: Going to high dimensions and beyond the likelihood ratio test Abstract: While machine learning (ML) has revolutionized nearly every aspect of experimental particle physics, the core hypothesis testing concepts have remained untouched, until now. In this talk, I will discuss how we can avoid summarizing data into low-dimensional histograms and […]
Title: Beyond Scores: Proximal Diffusion Models Abstract: Diffusion models have quickly become some of the most popular and powerful generative models for high-dimensional data. The key insight that enabled their development was the realization that access to the score— the gradient of the log-density at different noise levels— allows for sampling from data distributions by solving a […]
AstroCoffee seminars take place on Mondays at 10 AM and on Thursdays at 10 AM in the 5th Floor Lounge.
All department members are welcome for the department-wide colloquia series. Title: Revealing Exoplanet Atmospheres with Ground Based High Resolution Spectroscopy Abstract: With over 6,000 exoplanets now discovered, the field has entered a new era focused on characterizing their atmospheres, climates, chemistry, and formation histories. Over the past decade, advances in ground-based high-resolution spectroscopy have transformed […]
Discussions about black hole papers take place on Fridays at 10:30 am in Bloomberg 235, or on the patio, weather permitting.
AstroCoffee seminars take place on Mondays at 10 AM and on Thursdays at 10 AM in the 5th Floor Lounge.
The JHU/STScI CAS Wine and Cheese Seminars take place in Bloomberg 462 every Monday at 3:30 pm Eastern. Each week, there will be either one speaker, giving an hour-long presentation (50+10), or two speakers, each giving a half hour (25+5) presentation.
Science coffee is open to all department members for casual scientific discussions.
Title: Excitation Spectrum of Quantum Magnets Abstract: This seminar will focus on the spectrum of excited states of quantum many body systems, in the context of both experimental studies of magnets as well our theoretical understanding of quantum critical phenomena. I will introduce a numerical method that we have recently developed to study the finite […]
Title: The Tangled Dance of Higgs Decays: Spin Correlations and EFT
This seminar series probes some of the central questions in the physics of learning: What properties of data make it learnable? How is learned information encoded in neural representations? Do neural networks exhibit universal properties? Can we construct a thermodynamic theory of learning? What determines how performance scales with model size and computational resources?
