High Energy Seminar: "The Re-emergance of Spontaneously Broken Space-time Symmetries without Goldstones or Inverse Higgs"
Ira Rothstein (Carnegie Mellon)
In this talk I will discuss how broken space-time symmetries can emerge in the IR after being spontaneously broken in the UV, even though there may be no Goldstone bosons. Given that there has been a large body of…
Astro Seminar: POSTPONED UNTIL FALL
Zoltan Haiman (Columbia University)
POSTPONED UNTIL FALL
Advances in Biomedical Optics: "Theranostics Towards Point of Care Applications"
Israel Gannot (Johns Hopkins University and Tel-Aviv University)
My lab has been active developing Theranostics methods that utilize the advantages of different modalities for a synergetic combination for optimized clinical treatment. A main theme of the lab is bringing the…
Department Colloquium: "Simulating the self-assembly of nano-puzzles"
Daan Frenkel (Cambridge University) hosted by Tom Lubensky
A holy grail of nano-technology is to create truly complex, multi-component structures by self-assembly. Most self-assembly has focused on the creation of "structural complexity." In my talk, I will discuss "…
High Energy Seminar: "Large N Tensor Models"
Igor Klebanov (Princeton University)
We review the double line notation for the Feynman diagram expansion of N by N matrix models. In the ‘t Hooft large N limit only the planar diagrams survive, and the dual graphs may be thought of as discretized…
Diversity and Inclusion in Physics :"Women in Physics: Understanding and Overcoming Biases and Barriers"
Amy Graves (Swathmore)
Physics is phenomenally successful at taking data on sexless, raceless objects and transforming that information into mathematical laws with highly accurate predictive power. Why, therefore, should gender be an issue…
Condensed Matter Seminar: "Metal chalcogenide semiconductors: Synthesis, electronic structure, light-matter interactions"
Peter Sutter, University of Nebraska
Metal chalcogenides have received attention as two-dimensional (2D) materials beyond graphene. Semiconducting chalcogenides are particularly attractive since they exhibit novel physics such as strongly bound excitons…
Astro Seminar: "Investigation of Kepler-like Laws of Galactic Dynamics In Dispersion-supported Spherical Galaxies and Test of Dark Matter and Modified Gravity Theories"
Kyu-Hyun Chae (Sejong University)
Whether dynamical systems such as galaxies, galaxy clusters and the universe itself are controlled by Einstein’s theory of gravity in conjunction with yet-to-be-identified dark matter/energy or alternatively by…
