Astro Seminar: "A Possible First Detection of High-Redshift Population III Stars"
Eli Visbal (Columbia)
The recent observation of CR7 (Sobral et al. 2015), the brightest Lyman-alpha emitter at z~7, could be the first detection of Pop III stars (i.e. stars formed from primordial/extremely metal-poor gas). CR7 has strong…
Department Colloquium: "Physics Opportunities at Future Circular Colliders"
Liantao Wang (U of Chicago) Hosted by Joe Kroll
Following the discovery of the Higgs boson, there has been a lot discussion about the next step in high energy physics. Among different options, a couple of newly proposed next generation circular colliders,…
Special Energy Cluster Seminar: "Tailoring the flow of light at the nanoscale with hyperbolic metasurfaces"
Alexander High, Harvard University
Metamaterials offer unprecedented control of the flow of light at nanoscale dimensions, critical for the realization of compact, energy-efficient optical computing. However, three-dimensional (3D) metamaterials…
Condensed Matter seminar: "Valley and spin dependent physics in two-dimensional van der Waals’ materials"
Kin Fai Mak, Pennsylvania State University
Electrons in two-dimensional (2D) van der Waals’ materials with a honeycomb lattice structure possess both the valley pseudospin and the spin degree of freedom (DOF). The valley DOF is associated with the degenerate…
Astro Seminar: "Cross Correlations with CMB Secondaries: Constraining Cosmological Parameters and Cluster Astrophysics"
Nicholas Battaglia (Princeton)
High resolution CMB experiments, such as ACT, SPT, and the Planck satellite are making precision measurements of the secondary anisotropies caused by the thermal Sunyaev Zel'dovich (tSZ) effect from galaxy clusters.…
Special Energy Cluster Seminar: "Quantum physics to address global energy challenges"
Michael Biercuk, University of Sydney
Quantum physics research is providing surprising new avenues to solve longstanding challenges in energy - from lossy power distribution systems to inefficient large-scale fertilizer production. In this talk, I…
CTL Departmental Workshop
Philip T. Gressman (UPenn, Math)
Topic discussion on "Designing Your Own Course"
Graduate Students of Math, AMCS and other related departments are highly recommended to join in. This counts toward the CTL teaching certificate.

Condensed Matter seminar: "Network-based computational tools for the investigation of meso-scale structure in soft materials"
Danielle Bassett, University of Pennsylvania
Soft materials can display heterogeneous physical structure at the meso-scale, which can constrain mechanical stability and acoustic transmission. The need to understand such bulk properties motivates the development of…
Astro Seminar: "Simulating the Effect of Massive Neutrinos on Large Scale Structure"
Simeon Bird (Johns Hopkins)
The massive neutrino background makes up a component of the dark matter, and as such affects the growth of large-scale structure, such as galaxy clusters. This affords us an opportunity to measure the neutrino mass…
