  • Astronomy seminar: "The Hunt for Exomoons"

    David Rittenhouse Laboratory, A6

    David Kipping, Columbia University

    Since astronomers first started detecting exoplanets, interest in possible exomoons soon followed. Moons could be habitable worlds in their own right but also influence the habitability of planets they orbit. Besides from habitability, discovering moons would provide rich insights into the formation and evolution of planetary systems, potentially revealing the banality/uniqueness of our own solar system’s architecture.

  • Condensed Matter Seminar: "Taming Quantum Entanglement"

    David Rittenhouse Laboratory, A6

    Matthew Fisher, University of California, Santa Barbara

    Non-local quantum entanglement - “spooky action at a distance” - is the key feature that dis- tinguishes quantum from classical systems. The entanglement-entropy provides a measure of en- tanglement and for many-body systems is intimately connected to the thermal-entropy. Out of equilibrium, in a driven system or after a quantum quench, entanglement spreads ballistically with maximal entropy attained at long times - that is, complete disorder reigns. But not (always!) with life on earth! Why?

  • Condensed Matter Seminar: "Adhering, wrapping, and bursting of fluid membranes: understanding effects of membrane-binding particles and polymers"

    David Rittenhouse Laboratory, A6

    Anthony (Tony) Dinsmore, University of Massachusetts, Amherst

    Proteins and membranes form remarkably complex structures that are key to intracellular compartmentalization, cargo transport, and cell morphology. Despite this wealth of examples in living systems, we still lack design principles for controlling membrane morphology in synthetic systems. With experiments and simulations, we show that even the simple case of spherical nanoparticles binding to lipid-bilayer membrane vesicles results in a remarkably rich set of morphologies that can be reliably controlled via the particle binding energy.

  • Condensed Matter Seminar: "Revisiting and Repurposing the Double Helix"

    David Rittenhouse Laboratory, A6

    Taekjip Ha, Johns Hopkins University

    DNA is an iconic molecule that forms a double helical structure, providing the basis for genetic inheritance, and its physical properties have been studied for decades. In this talk, I will present evidence that sequence and methylation dependent physical properties of DNA such as flexibility and self-association may be important for biological functions [1, 2]. In addition, I will present a new application of DNA where mechanical modulations of cell behavior can be studied at the single molecule level using rupturable DNA tethers [3].
