Gravitational-Wave Asteroseismology: Illuminating Dense Nuclear Matter through Dynamical Tides Neutron stars present the tantalising opportunity to examine physics in a range of extreme regimes, including ultra-dense nuclear matter. Gravitational radiation from inspiralling compact binaries carries information about the deformability of the stellar material. However, the focus has primarily been on the static tide. Much like […] |

Title: The Cross-Disciplinary Hunt for Dark Matter: ML and Material Science Meet Astroparticle Physics Abstract: The age of WIMP-like dark matter direct detection is drawing to a close due to their non-detection at exquisitely sensitive liquid-noble detectors. However, models where the dark matter is lighter than the mass of a proton remain largely inaccessible to […]

All department members are welcome for the department-wide colloquia series. Title:The Return of Anyons: From twisted layers to quantum platforms Abstract: What if matter were built of particles that follow different rules than the ones we've known for a century? While conventional particles are either bosons or fermions, theory has predicted the existence of "anyons"—particles […] |

Title: Efficient Finetuning of Large Language Models via Large-WidthAnalysis Abstract: Finetuning Large Language Models (LLMs) enhances their performance on downstream tasks — a desirable outcome if the model is used for a specific task.Parameter-efficient finetuning methods such as LoRA (Low-Rank Adaptation) are popular because they allow finetuning large models with relatively low cost. When using […]

All department members are welcome for the department-wide colloquia series. Title: Quantum Field Theory, Separation of Scales, and Beyond Abstract: We will review the role of Quantum Field Theory (QFT) in modern physics. We will highlight how QFT uses a reductionist perspective as a powerful quantitative tool relating phenomena at different length and energy scales. […] |

Title: Learning normalized probability models with dual score matching Abstract: Learning probability models from data is at the heart of many learning tasks. We introduce a new framework for learning normalized energy (log probability) models inspired from diffusion generative models. The energy model is fitted to data by two "score matching" objectives: the first constrains […] |

Title: Floquet and cavity electrodynamics of integrated quantum materials Abstract: Quantum materials exhibit emergent phenomena driven by interactions, topology, and dimensionality. My group develops techniques for integrating microstructured quantum materials and heterostructures into on-chip optoelectronic devices, enabling both the manipulation and direct probing of their low-energy electrodynamics on femtosecond timescales and terahertz (THz) frequencies. In […]

Title: Quantum-Limited Macroscopic NMR Abstract: Nuclear magnetic resonance (NMR) is one of the pioneering quantum information/measurement techniques. It has found applications ranging from medical imaging to precision tests of the fundamental physics of our universe. In this talk, I introduce the standard quantum limit for NMR detection sensitivity that comes from intrinsic quantum fluctuations known as […]

Title: What Does Adam Really Need? Understanding Second Moment Compressibility Through Training Dynamics Abstract: Adam is the go-to optimizer for training modern machine learning models, but it requires additional memory to maintain the moving averages of the gradients and their squares. Despite its success, a fundamental question remains unanswered: When can Adam's second moments be […] |

Title: Quantum signatures and decoherence during inflation from primordial gravitational waves Abstract: In order to shed light on the quantum to classical transition of the primordial perturbations in single field inflation, we investigate the decoherence and associated quantum corrections to the correlation functions of large-scale (superhorizon) scalar curvature perturbations. The latter are considered as an open […] |

Title: New perspectives on primordial black hole formation and abundance The possibility of primordial black holes (PBHs) forming in the early Universe from the collapse of cosmological perturbations has received lots of attention in the last ten years after the first detection of gravitational waves. PBHs span a very wade range of masses, from the […] |

Title: The Three P's of Modern Computer Vision: Pixels, Perception and Physics Abstract: For decades, computer vision has been defined by three grand challenges, elegantly summarized by Jitendra Malik et al as the "Three R's": Recognition (what is it?), Reconstruction (what is its 3D shape?), and Reorganization (what belongs together?). While this framework has guided […]

Manuel Mariano Title: There and back again: outspiralling motion in non-Kerr compact objects Abstract: In Keplerian dynamics, a test body orbiting a point particle in circular motion has a monotonically increasing frequency, with decreasing radius. If a dissipative channel is introduced, such as gravitational wave (GW) emission, (say) under the quadrupole approximation, the corresponding GW strain […]

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 […]
