Mathematical Biology seminar: "Communicating by touch"

HyunJoong Kim (University of Utah)
- David Rittenhouse Laboratory, A6

During development, cells figure out their location and fate through morphogen concentration gradients.  The most commonly accepted mechanism for morphogen gradient formation is diffusion from a local source combined…



Condensed and Living Matter Seminar: "Fractons: From Theory to Realizations

Michael Pretko (University of Colorado)
- David Rittenhouse Laboratory, A6

Fractons are an exotic type of quasiparticle which have emerged as a new frontier for condensed matter physics, with potential applications to quantum information storage. The defining feature of these particles is…



Condensed and Living Matter Seminar: "Symmetry indicators for topological materials"

Adrian Po (Massachusetts Institute of Technology)
- David Rittenhouse Laboratory, A4

Topological materials are characterized by robust physical signatures, like anomalous surface states, that are derived from the topological distinction between their ground states and those of their…



Astronomy seminar: "Merging Supermassive Black Hole Binaries"

Zoltan Haiman (Columbia University)
-

Supermassive black hole (SMBH) binaries are inevitably produced during galaxy formation, but observational evidence for them remains elusive.  I will discuss the coupled dynamics of a SMBH binary…



Experimental Particle Physics Seminar: "Deep Learning, Quantum Information, and the LHC as a Gluon Factory"

Ben Nachman (LBNL)
- David Rittenhouse Laboratory, 2C6

Jets produced from high-energy quarks and gluons are ubiquitous at the Large Hadron Collider (LHC). These objects can be used to study emergent quantum properties of the strong force as well as search for new…



Condensed and Living Matter Seminar: "Electronically integrated cell sized robots"

Itai Cohen (Cornell University)
- David Rittenhouse Laboratory, A4

What would we be able to do if we could build electronically integrated machines the size of a single cell? At a scale of 50 microns, or about half…



High Energy Theory seminar: "Correlators of BPS lines in conformal field theory"

Philip Argyres (Cincinnati University)
- David Rittenhouse Laboratory, 2N31

We study the properties of correlation functions of conformal line operators in four-dimensional superconformal field theories.  These are treated as n-point functions on the configuration…



Physics and Astronomy Colloquium: "Interstellar Objects"

Greg Laughlin (Yale University)
- David Rittenhouse Laboratory, A8

During the past two years, two objects -- 1I 2017 'Oumuamua and C/2019 Borisov -- have been observed to pass through the Solar System after arriving from interstellar space. 'Oumuamua presented a series…
