Condensed Matter Seminar: "Ideas on magma motion within the lithosphere: percolation, channelization, and stress-driven segregation"
Mousumi Roy (University of New Mexico)
Although we know that magma is generated by partial melting of rocks at depth, we have less of an understanding of the processes that transport magma from great depths (>100-150 km) into the shallower (20-0 km)…
Astro Seminar: "Dark Matter Clustering in the Dissipationless Limit"
Michael Joyce (Sorbonne Université, Paris)
An accurate description and understanding of matter clustering in the strongly non-linear regime, even neglecting baryonic physics, remains a problem which is relevant to cosmology and of fundamental interest. My…
HET & HEE Joint Seminar: "Cosmological Bounces and Wormholes from Vorticity"
David Kaplan (John Hopkins University)
High Energy Theory Seminar: (TBA)
Ted Jacobson (U of Maryland)
Workshop on Imaging Biomarkers
Welcome to the Fifth Annual CMROI Workshop on Imaging Biomarkers to be held Thursday, March 22nd, 2018 at the Biomedical Research Building II/III of the Perelman School of Medicine at the University of Pennsylvania…
Condensed Matter Seminar: "Geometry and mechanics of feet and fins"
Mahesh M. Bandi (Okinawa Institute of Science and Technology Graduate University)
The stiffness of propulsive appendages, such as feet and fins, is important in locomotory function. In this talk, I show that curvature-induced stiffness is the common principle underlying the stiffness of both…
High Energy Theory Seminar: "Discrete Superconformal Matter"
Paul Oehlmann (Virginia Tech)
We construct a novel type of (2,0) discrete charged superconformal matter coupled to 6d supergravity using F-theory. For this, we consider smooth genus-one fibered and compact Calabi-Yau threefolds quotiented by a…
Astro Seminar: "Insights Into Dark Matter From the Stellar Halos of Galaxies"
Robyn Sanderson (Caltech)
Cosmological simulations can now make specific and detailed predictions for the shapes, masses, and substructure fractions in galactic dark matter halos that depend on the dark matter model assumed. Comparing these…
Primakoff Lecture: "Metamaterials and Topological Mechanics"
Tom Lubensky (University of Pennsylvania)
Metamaterials are materials engineered to have a property or properties not found in nature, such as a negative optical index of refraction, one-way light or vibration waves, or exotic elastic behavior. Advances in…
