  • Condensed Matter Seminar: "Physics and Applications of Mesoscopic Optics"

    David Rittenhouse Laboratory, A6

    Hui Cao, Yale University

    Random scattering of light, e.g., in paint, clouds, and biological tissue, is a common process of both fundamental interest and practical relevance. The interference of multiply scattered waves also leads to remarkable phenomena in mesoscopic physics such as Anderson localization and universal conductance fluctuations. In applications, optical scattering is the main obstacle to imaging or sending information through turbid media.

  • Astronomy seminar: "Cosmological Seed Magnetic Field from Inflation"

    David Rittenhouse Laboratory, A6

    Bharat Ratra, Kansas State University

    A cosmological magnetic field of nG strength on Mpc length scales could be the seed magnetic field needed to explain observed few microG large-scale galactic magnetic fields. I first briefly review the observational and theoretical motivations for such a seed field, two galactic magnetic field amplification models, and some non-inflationary seed field generation scenarios. I then discuss an inflation magnetic field generation model. I conclude by mentioning possible extensions of this model as well as potentially observable consequences.

  • Condensed Matter Seminar: "Soft Matter Physics of the Evolution of Multi-Cellularity"

    David Rittenhouse Laboratory, A6

    Peter Yunker, Georgia Institute of Technology

    The evolution of multicellularity set the stage for an incredible increase in the diversity and complexity of life on Earth. The increase in biological complexity associated with multi-cellularity required parallel innovation in the mechanical properties of multi-cellular bodies. Though a cursory review of any multi-cellular organism provides an appreciation of this intertwining of biological and mechanical complexity, little is known about how such mechanical properties may have evolved.

  • Condensed Matter Seminar: "Geometrically frustrated self-assembly: what determines the dimensionality of the aggregates?"

    David Rittenhouse Laboratory, A6

    Pierre Ronceray, Princeton University

    Irregularly shaped particles with attractive interactions, such as proteins or patchy colloids, are in general frustrated: it is impossible to arrange them in space such that all attractive interactions are simultaneously satisfied. In a dense phase, this implies that any configuration must include defects to the favoured local order.
