In This Series

  1. A Half Century of Nonlinear Optics

    22 Mar 2011 | Online Presentations | Contributor(s): Robert W. Boyd

    In this talk, we first present a review of the development of the field of nonlinear optics, and we then survey some areas of recent research including quantum imaging and implications of the ability to control the group velocity of light.

  2. Putting the Electron’s Spin to Work

    14 Apr 2011 | Online Presentations | Contributor(s): Daniel Ralph

    I will discuss recent progress in experimental techniques to control the orientations of nanoscale magnetic moments and electron spins, and to use these new means of control for applications. One powerful new capability arises from the fact that thin magnetic layers can act as filters for spins.

  3. Nanoscale Spectroscopy and Plasmonics in Infrared

    19 Apr 2012 | Online Presentations | Contributor(s): Mikhail Belkin

    In this talk, I will present the results of two of our research projects. I will start with a simple technique for nanoscale mid-infrared spectroscopy that we have developed recently. Subwavelength resolution is achieved by detecting optical absorption through measuring local photothermal...

  4. Nanoscale Electrothermal Energy Transport

    12 Jul 2013 | Online Presentations | Contributor(s): Ali Shakouri

    Thermoreflectance imaging is used to study Peltier cooling and Joule heating in devices with 800ps time and submicron spatial resolution. The ballistic heat conduction and the transition between energy and entropy transport in ultra short times and in thin film devices will be discussed. Finally...

  5. The Secret Life of Electrons in High Temperature Superconductors

    19 Jun 2013 | Online Presentations | Contributor(s): Erica W. Carlson

    Purdue University Department of Physics REU,National Science Foundation

  6. Physics of the Piano

    12 Jul 2013 | Online Presentations | Contributor(s): Nicholas J. Giordano

    Why does a piano sound like a piano? A similar question can be asked of virtually all musical instruments. A particular note, such as middle C, can be produced by a piano, a violin, and a clarinet. Yet, it is easy for even a musically untrained listener to distinguish between these instruments....

  7. Catching Sunlight: Lessons from Photosynthesis

    10 Jul 2013 | Online Presentations | Contributor(s): Sergei Savikhin

    We will discuss the physics of early processes in photosynthesis revealed by ultrafast laser spectroscopy.

  8. Quantum Band Engineering in III-nitride Semiconductors

    12 Oct 2013 | Online Presentations | Contributor(s): Oana Malis

    In this talk I will focus on our efforts to creatively exploit the unique properties of nano-structured III-nitride materials for novel light emitters and detectors in the currently under-developed near- and far-infrared ranges. Due to large electron effective mass, the nitride intersubband...

  9. Sequencing a Genome by a Torrent of Ions: How an Old pH-Meter Got Its Groove Back

    11 Apr 2014 | Online Presentations | Contributor(s): Muhammad A. Alam

    The ability to read the book of life, written in the genome of an organism, has been one of the most exciting development of our time. The first version of human genome was announced circa 2000 and it took a decade of industrial-scale collaboration and billions of dollars of funding. Today, we...

  10. Strain Engineering of 2D Crystals

    08 Oct 2014 | Online Presentations | Contributor(s): Bennett Goldberg

    Two-dimensional materials are flexible, transparent, compatible with living systems, and can enable new devices and physics based on their unique properties. One unique property is the ability of 2D crystals a single atom thick to undergo massive amounts of strain without failure. Since strain...

  11. Incorporation of Studio Exercises for Physics Instruction at all Levels

    11 Dec 2014 | Online Presentations | Contributor(s): Christopher M. Sorensen

    In this talk I will give examples of studio activities from all three and observations with regard to how well this form of instruction works. I will also discuss problems incurred with regard to class size and time limitations. My goal is to encourage my audience to implement studio instruction...

  12. Of Soot and Sunflowers

    16 Dec 2014 | Online Presentations | Contributor(s): Christopher M. Sorensen

    In this talk I will describe some of my researches into soot and other aggregate structures; an unlikely journey of discovery to find fractal structures with non-Euclidian dimensionality, gel networks of graphene that tenuously span space and common Fibonacci themes between spirals, sunflowers...
