Astro Seminar: "Exodynamos: Magnetic Field Generation and Detectability"
TBD
Planetary magnetic fields are ubiquitous in the Solar System and extrasolar planets are common in the galaxy. However, no extrasolar planetary magnetic field (or exodynamo) has yet been directly detected. Magnetic…
Condensed Matter seminar: "Braiding Light"
Claudio Chamon, Boston University
Many topological phenomena first proposed and observed in the context of electrons in solids have recently found counterparts in optical and acoustic systems. In this talk I will discuss non-Abelian Berry phases that…
Astro Seminar: "Beyond Pluto: The Hunt for Planet X"
Scott Sheppard (Carnegie Institution for Science)
The Kuiper Belt, which has Pluto as the largest member, is a region of comet like objects just beyond Neptune. This belt of objects has an outer edge, which we are now only able to explore in detail. For the past…
ABO Seminars: "Label-free Optical Micro Imaging of Tissue Histology in Vivo"
Xingde Li (Johns Hopkins University)
This seminar will focus on our recent progresses on developing high-resolution biophotonic imaging technologies, particularly the second-generation optical coherence tomography (OCT) endoscopy and multiphoton…
Department Colloquium: "The Universe as a Lab for Fundamental Physics: Results from Spider and Future Suborbital Missions"
William Jones (Princeton) Hosted by James Aguirre
I will describe our recent results from observations of the Cosmic Microwave Background, including a status report on the recent flight of the Spider experiment, a balloon borne CMB polarimeter. I will also discuss…
Condensed Matter seminar: "Wavefront Shaping for in vivo Brain Imaging"
Na Ji, Janelia Research Campus
There are about the same number of stars in our galaxy as there are neurons in our brain. To study stars and neurons using optical imaging, we face similar challenges of image degradation by aberrations and…
Condensed Matter seminar: “Do entangled polymers possess a shear banding instability?”
Peter Olmsted, Georgetown University
The original Doi-Edwards theory (1978) predicted that long entangled polymers should become unstable to homogeneous shear flow for shear rates exceeding the relaxation (reptation) time. At the time this seemed to…
