High Energy Theory Seminar: Coherence in the sky: from precision astrometry to black holes and hidden particles
Masha Baryakhtar (U. Wash)
In the era of a wealth of data from the sky, new perspectives can lead to parametric improvements in discovery reach. I will discuss two ideas that make use of surprising properties of coherent radiation to open new…
Condensed and Living Matter Seminar: Topological Defects in Computational Meshing
David Palmer (Harvard University)
The topological structure of a hexahedral mesh is characterized by its singularities, which look like line disclinations in a crystal. In field-based meshing, one first computes a so-called octahedral…
Experimental Particle Physics Seminar: Muon trigger system and search for supersymmetry
Kaito Sugizaki (University of Tokyo)
The ATLAS experiment, consisting of over 3,000 members, explores new frontiers in physics with high-energy proton-proton collisions at the LHC. In such a large collaboration, it is crucial to devote oneself to…
Astrophysics Seminar: Constraining Galaxy Formation And Baryonic Effects On LSS With Observations Of The Thermal And Kinetic SZ Effects
Nick Battaglia (Cornell University)
A new window into the growth and evolution of large-scale structure has opened up with the recent observations of the thermal and kinetic Sunyaev-Zel’dovich (SZ) effects. I will…
High Energy Theory Seminar: de Sitter as an Axion Detector
John Stout (Harvard)
Axions, scalar fields with compact field spaces, are some of the most well-motivated candidates for physics beyond the Standard Model. In this talk, I will explain how inflationary correlations are uniquely sensitive…
High Energy Theory Seminar: Squaring Charges and finding Black Holes
Mariana Carrillo Gonzalez (Imperial)
Nowadays, we have an outstanding grasp of gauge theories on both experimental and theoretical fronts. Meanwhile, our understanding of gravitational physics has advanced greatly, but many mysteries remain…
Astrophysics Seminar: ML x Cosmology with 50 Million Galaxies
ChangHoon Hahn (Princeton University)
The 3D spatial distribution of galaxies encodes key cosmological information that can be used to probe the nature of dark energy and measure the sum of neutrino masses. The next…
Experimental Particle Physics Seminar: Search for Emerging Jets at CMS
Yi-Mu Chen (University of Maryland)
I present the search for emerging jets produced in proton-proton collisions at a center-of-mass energy of 13 TeV performed using data collected by the CMS experiment corresponding to an integrated luminosity of 138…
Condensed and Living Matter Seminar: Magnetic imaging of domain walls and surface transition in antiferromagnetic topological insulators
Weida Wu (Rutgers University)
Layered antiferromagnets with topological band structure are promising platforms to host many interesting topological phenomena. Thus, it is imperative to visualize domains or…
High Energy Theory Seminar: In search of a Higgsino
Weishuang Linda Xu (Lawrence Berkeley National Laboratory)
The search for dark matter is indisputably now a multi-disciplinary and multi-decadal effort.
