Experimental Particle Physics Seminar: The mystery of cold noise in ATLAS upgrade silicon strip modules
Ian Dyckes (LBNL)
In preparation for the High Luminosity LHC, the ATLAS Experiment is constructing a new Inner Tracker (ITk) composed of silicon pixel and silicon strip detectors. After multiple years of prototyping, the ITk strips…
Condensed Matter Seminar: Cell motility and shape as a playground for physics
Brian Camley (Johns Hopkins University)
Cells crawl and reorganize in the body to perform their functions, ranging from white blood cells finding bacteria to skin cells closing over a wound. These behaviors provide huge opportunities for…
High Energy Theory Seminar: Probing dark matter with cosmic voids
Elena Pinetti (Fermi National Accelerator Laboratory)
In this talk, I will explain why cosmic voids are an interesting new target for dark matter searches. I will show that the expected signal-to-noise ratio resulting from decaying dark matter is significantly more…
Astrophysics Seminar: Looking at the sky with artificially intelligent eyes
Gautham Narayan (University of Illinois Urbana-Champaign)
Time-domain astrophysics is entering a golden age with discovery rates increasing exponentially thanks to combining public and private surveys such as the Young Supernova…
Condensed Matter Seminar: Quantum geometry in semiconductor heterostructures
Raquel Querioz (Columbia University)
Quantum geometry quantifies the momentum space textures of the Bloch wavefunctions and impacts substantially the physics of multiband systems. This is also true for van der Waals semiconductors, which are…
High Energy Theory Seminar: Light States across Field Space
Max Wiesner (Harvard University)
A common feature of theories of quantum gravity is the presence of light, massive states beyond those described by effective field theory. The species scale gives a measure for the number of such light states and…
Astrophysics Seminar: Old meets new when drones meet CHIME: calibration instrumentation for 21cm cosmology
Laura Newburgh (Yale University)
Current cosmological measurements have left us with deep questions about our Universe: What caused the expansion of the Universe at the earliest times? How did structure form? What is Dark Energy and does it evolve with…
Experimental Particle Physics Seminar: Defying 4D Gravity: Novel searches for signatures of string theory via scalar cascades, noncommutative black holes, non-minimal dark sectors, and deep learning
Elena Villhauer (University of Edinburgh)
The existence of extra dimensions could lower the fundamental Planck scale to the low TeV scale and very excitingly allow string theory to be probed at the LHC. This talk introduces novel searches for signatures of…
Condensed Matter Seminar: Self-Organization of Wave-Matter Composite Systems
David Grier (New York University)
Optical tweezers and acoustic traps use forces exerted by waves to confine small objects in three dimensions and to transport them along pre-programmed trajectories. This is not the end of the story…
High Energy Theory Seminar: Normalization of Instantons in Minimal String Theory
Chitraang Murdia (University of Pennsylvania)
We match instanton contributions between minimal string theory and its dual matrix integral. The main technical insight is to use string field theory to analyze and cure the divergences in the cylinder diagram in…
