  • Condensed Matter Seminar: "Single-molecule force spectroscopy: Theory meets experiment"

    Room A4, DRL22

    Olga Dudko, U.C. San Diego

    Single-molecule biophysical tools are making it possible to measure the response of individual biomolecules to external force – in real time and with unprecedented resolution – revealing information that is typically lost when studied though traditional “bulk” methods. I will present a general analytical theory of force-induced molecular transitions. The theory is based on Kramers picture of diffusive barrier crossing and on a generalization of this picture to many dimensions.

  • Condensed Matter Seminar: "Topological Edge States at a Tilt Boundary in Gated Multilayer Graphene"

    A4 DRL

    Eun-Ah Kim , Cornell University

    Despite much interest in engineering new topological surface (edge) states using structural defects, such topological surface states have not been observed yet. We show that recently imaged tilt boundaries in gated multilayer graphene should support topologically protected gapless edge states. We approach the problem from two perspectives: the microscopic perspective of a tight-binding model and an ab initio calculation on a bilayer, and the symmetry-protected topological (SPT) state perspective for a general multilayer.

  • Tesla: Inventor of the Electrical Age

    Penn Bookstore, 3601 Walnut Street

    W. Bernard Carlson, Prof of Science and Technology, School of Engineering and Applied Science

    In “Tesla,” Carlson examines the life and work of celebrity scientist Nikola Tesla. While many have glamorized Tesla and his eccentricities, Carlson offers an honest look at the what, how and why behind his inventions.

    Nikola Tesla was a major contributor to the electrical revolution that transformed daily life at the turn of the 20th century. Like his competitor Thomas Edison, Tesla was one of America’s first celebrity scientists, cultivating a public image of the eccentric genius.
