High Energy Theory Seminar: Black Holes as Probes for Ultralight Dark Matter
Bruno Bucciotti (Scuola Normale Superiore)
I will discuss the possibility that dark matter is made of weakly interacting, very light scalar particles, briefly reviewing the strong theoretical motivations of this proposal. In a scenario where non-gravitational…
Center for Soft and Living Matter Special Seminar: Medium-range order and local structure fluctuations in metallic glass
Professor Xun-Li Wang, City University of Hong Kong
Amorphous materials have no long-range order, but there are ordered structures at short-range (2-5 Å), medium-range (5-20 Å), and even longer-length scales. While regular and semiregular polyhedra are…
Colloquium: Global Famine after Nuclear War
Alan Robock (Rutgers University)
The world as we know it could end any day as a result of an accidental nuclear war between the United States and Russia. The fires produced by attacks on cities and industrial areas would generate smoke that would…
High Energy Theory Seminar: MIT and Black Hole Initiative at Harvard University
Thomas Steingasser (MIT)
The SM Higgs sector is subject to two fine-tunings, manifesting in the hierarchy problem and the metastability of the electroweak vacuum. I will explain why these tunings, which were long believed to be independent,…
Condensed and Living Matter Seminar: “Fractal patterns in music”
Andrzej Herczyński (Boston College)
If aesthetic preferences are influenced by the fractal geometry of nature, scaling regularities would be expected in all art forms, including music. While a variety of statistical tools have been proposed to analyze…
Astrophysics Seminar: From Stars to Quasars: Microlensing as a Tool for Galactic and Extra-galactic Discovery
Somayeh Khakpash (Rutgers University)
By analyzing the gravitational lensing effects of stars and planets in our galaxy, and other massive distant galaxies, microlensing provides unique insights into phenomena that are otherwise difficult to observe. In…
High Energy Theory Seminar: The dynamics of dRGT massive gravity
Jan Kożuszek (Imperial College London)
After reviewing the motivation and challenges connected with the dRGT theory of ghost-free massive gravity, we discuss our recent progress in understanding non-linear dynamics of this model. In spherical symmetry,…
Astrophysics Seminar: The Present and Future of High-Energy Neutrino Astronomy
Naoko Kurahashi Neilson (Drexel University)
In the past decade, neutrino astronomy went from dream to reality with IceCube producing spectacular observations of the very first neutrino sources in the sky. Last year, the diffuse emission of the Galactic Plane…
Condensed and Living Matter Seminar: Key issues in understanding the superconductivity of UTe2
Johnpierre Paglione (University of Maryland)
The spin-triplet superconductor UTe2 has recently emerged as a rich system that incorporates aspects
of unconventional superconductivity, heavy-electron physics and non-trivial topologies.

Experimental Particle Physics: Expanding Horizons: Novel Strategies in low mass BSM Physics Exploration with CMS
Abhijith Gandrakota (Fermilab)
In the pursuit of Beyond the Standard Model (BSM) physics, the CMS experiment has employed unconventional techniques to uncover elusive phenomena. This presentation delves into three pivotal aspects of this effort…
