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…
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…
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…
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…
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.
High Energy Theory Seminar: Mapping New Physics from the UV to the IR
Grant Remmen (NYU)
Using a combination of techniques spanning the modern amplitudes program, string theory, effective field theory, cosmology, and particle physics, I will show how the space of the possibilities for new…
Colloquium: The Dawn of Gravitational Wave Astronomy at Light-year Wavelengths
Stephen Taylor (Vanderbilt University)
For more than 15 years, NANOGrav and other pulsar-timing array collaborations have been carefully monitoring networks of…
