Title: Smart microscopy reveals patterns underlying the mitochondrial life cycle Abstract: As ancient endosymbionts mitochondria maintain their own minimal genome and support a quasi-life cycle. They form dynamic networks transitioning between a highly interconnected reticulum and disassociated individuals. They also take on complex branched and pearled shapes. How these dynamics serve the mitochondrial life cycle of […]

All department members are welcome for the department-wide colloquia series. Title: Deep Learning: Some Perspectives from Physics Abstract: Over the past decade, our theoretical understanding of deep learning has expanded significantly, even if it still lags behind the pace of practical breakthroughs. This talk will trace how our conceptual picture has evolved—from early misconceptions to […] |

Title: Mitigating the Curse of Detail: Scaling Arguments for Feature Learning and Sample Complexity Abstract: Two pressing topics in the theory of deep learning are the interpretation of feature learning mechanisms and the determination of the implicit bias of networks in the rich regime. Current theories of rich feature learning effects revolve around networks with […] |

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 […] |

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 […] |

Title: Towards experimentally testing the quantum nature of gravity. Abstract: Testing the quantum nature of gravity in the laboratory has become an exciting frontier. A leading proposal is to demonstrate quantum entanglement between massive objects mediated solely by their Newtonian gravitational interaction. At the same time, “classical” models of gravity—where a classical field couples to […] |

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
-
Title: Towards a theory of hierarchical representation learning Abstract: Deep neural networks trained on natural data spontaneously develop hierarchical internal representations that mirror the compositional structure of the world. From the emergence of phonemes, syntax, and semantics in large language models to the layered organisation of visual features in convolutional networks, these systems learn to […] |

All department members are welcome. Title: What do the fundamental constants of physics tell us about life? Abstract: In the 1970s, the renowned physicist Victor Weisskopf famously developed a research program to qualitatively explain properties of matter in terms of the fundamental constants of physics. But there was one type of matter prominently missing from […] |

Canonical Quantization of General Relativity and Quantum Resolution of Cosmological Backgrounds The main goal of this talk is to demonstrate that the canonical quantization of General Relativity, within BRST-invariant framework, leads to the healthy Hamiltonian flow. In particular, I will show that the classical properties of Einstein's gravity, such as vanishing bulk Hamiltonian, is realized […] |

Un-Detecting Dynamical Dark Energy in DESI's data Dark matter, dark energy, the Hubble tension, and cosmic inflation remain central challenges in cosmology and particle physics. These challenges have sharpened with recent reports favoring evolving dark energy by the DESI collaboration. I will present a program of addressing these challenges using full-shape large-scale-structure analyses based on […] |

Location: JHU, Bloomberg building, room 462 Speaker: Raman Sundrum (UMD) Title: Interplay between high-energy and low-energy experiments in light of BSM theory Abstract: I will describe and update the comprehensive theoretical frameworks capable of explaining the hierarchical structure of particle physics and how they present diverse ambitious targets for high-energy colliders. These targets include WIMP dark matter and SUSY, […]

Title: Topology You Can See: Liquid Crystalline Defects and Broken Translational Symmetry Abstract: Topology has become an indispensable tool across all areas of physics. Defects in liquid crystals provide a classic application of topology: unremovable singularities are assigned a topological charge according to a symmetry-based procedure from homotopy theory. In this talk I will discuss topological defects in smectic […]
