Condensed and Living Matter Seminar: Van der Waals magnets and antiferromagnets interacting with electron spins

Dan Ralph (Cornell University)
- David Rittenhouse Laboratory A8

This talk will discuss two projects.  The first concerns topological insulator/magnet samples made by mechanical stacking of exfoliated van der Waals flakes.  The proximity…



Astrophysics Seminar: Mapping Cosmic Star Formation with the CO Mapping Array Project

Patrick Breysse (NYU)
- David Rittenhouse Laboratory, 4E19

I will discuss the results of the second observing season of the CO Mapping Array Project (COMAP).  COMAP is a line intensity mapping experiment seeking to probe the cosmic star formation history by mapping the…



High Energy Theory Seminar: Apparent Fine Tunings for Field Theories with Broken Space-Time Symmetries

Alberto Nicolis (Columbia University)
- David Rittenhouse Laboratory, 3W2

I will exhibit a class of effective field theories that have hierarchically small Wilson coefficients for operators that are not protected by symmetries but are not finely tuned. These theories possess bounded target…



Profs & Pints Philadelphia: Finding the Cosmic Puzzle's Missing Pieces

Mark Trodden (UPenn)
- Black Squirrel Club 1049 Sarah St Philadelphia, PA 19125

Profs and Pints Philadelphia presents: “Finding the Cosmic Puzzle’s Missing Pieces,” a look at how the fields of astronomy and subatomic physics are working in tandem to shed light on the darkest parts of the…



Condensed and Living Matter Seminar: "Robots that evolve on demand"

Rebecca Kramer-Bottiglio (Yale)
- David Rittenhouse Laboratory A8

Abstract: Soft robots have the potential to adapt their morphology and behavioral control policy to changing tasks and environments. Inspired by the dynamic plasticity of living materials and general adaptability of…



Astrophysics Seminar: Exploring solutions to the galaxy diversity problem

Akaxia Cruz (Flatiron Institute/Princeton University)
- David Rittenhouse Laboratory, 4E19

On large scales the Universe is well described by a cosmological model where matter primarily comprises cold dark matter (CDM), a single collision-less particle species with negligible primordial thermal dispersion.…



High Energy Theory Seminar: Causality constraints on EFTs

Sera Cremonini (Leigh University)
- David Rittenhouse Laboratory, 3W2

I will discuss how causality can be used to place bounds on higher derivative corrections to Einstein Maxwell theory. Scattering probe photons off of charged shock waves, we obtain new constraints on the Wilson…



Colloquium: The Wide-angle View of Dark Matter in Nearby Galaxies

Robyn Sanderson (University of Pennsylvania)
- David Rittenhouse Laboratory, A8

The Gaia astrometric survey has delivered a detailed “close-up” of our Galaxy, the Milky Way, by measuring precise 3D positions and…



High Energy Theory Seminar: "TBA"

Brian McPeak (McGill University)
- David Rittenhouse Laboratory, 3W2



Condensed and Living Matter Seminar: Multicellular is different: the biophysical basis of multicellular growth

Peter Yunker (Georgia Tech)
- David Rittenhouse Laboratory A8

Cells often live in groups, such as surface attached communities of unrelated bacteria (e.g., biofilms) to multicellular organisms (e.g., animals). Living in groups provides cells with a range of…
