    Rechtsman, Mikael C. (Georgia Institute of Technology, 2018-05-15)
  • Higher Order Topological Insulators: Quadrupoles and Beyond 

    Hughes, Taylor (Georgia Institute of Technology, 2018-05-15)
  • Defect Unbinding in Active Nematic Tori 

    Fernandez-Nieves, Alberto (Georgia Institute of Technology, 2018-05-15)
    We will discuss our recent results with active nematics on toroidal surfaces and show how, despite the intrinsic activity and out-of-equilibrium character of our system, we still observe remnants of the expected curvature-induced ...
  • Active Fluids as Topological Metamaterials: Structure Without H Periodic Order 

    Souslov, Anton (Georgia Institute of Technology, 2018-05-15)
    Active liquids are composed of self-driven microbots that endow the liquid with a unique set of mechanical characteristics. We present two designs for topological states using active fluids: one using periodic confinement ...
  • Flocks on a Sphere Sound Topological! 

    Shankar, Suraj (Georgia Institute of Technology, 2018-05-14)
    Flocking, the self-organized and spontaneous motion of a large collection of self-propelled entities, is ubiquitous in the natural world. Such collective motion, for instance in groups of cells advancing en masse during ...
  • Topological Protected Modes in Non-equilibrium Stochastic Systems 

    Vaikuntanathan, Suri (Georgia Institute of Technology, 2018-05-14)
    Non-equilibrium driving of biophysical processes is believed to enable their robust functioning despite the presence of thermal fluctuations and other sources of disorder. Such robust functions include sensory adaptation, ...
  • Topological Edge Floppy Modes in Disordered Fiber Networks 

    Mao, Xiaoming (Georgia Institute of Technology, 2018-05-14)
    Disordered fiber networks are ubiquitous in natural and manmade materials. The dilute nature of these networks permits floppy modes which only bend the fibers without changing their length, and these floppy modes govern ...
  • Topological Patterning of Polymers on a Substrate 

    Paulose, Jayson (Georgia Institute of Technology, 2018-05-14)
    Thermal fluctuations and interactions often complicate or even ruin topological phenomena, yet are an inherent part of soft matter systems and a prime source of messiness. I'll describe a system of substrate-adsorbed ...
  • Persistence of Topological Invariants Under Disorder 

    Bellissard, Jean (Georgia Institute of Technology, 2018-05-14)
    A review of the techniques on Non-commutative Geometry to express rigorously the topological invariants, like in the Quantum Hall Effect or Topological Insulators will be provided. It will include some numerical work by ...
  • Topological Patterns 

    Prodan, Emil (Georgia Institute of Technology, 2018-05-14)
    The research in topological materials and meta-materials reached maturity and is now gradually entering the phase of practical applications and devices. However, scaling down the experimental demonstrations definitely ...
  • Vibration Location in Quasi-Periodic Beams and Plates 

    Ruzzene, Massimo (Georgia Institute of Technology, 2018-05-14)
    The talk will present ongoing investigations on elastic wave propagation in quasi-periodic beams and plates. Results show the occurrence of a variety of modes that are localized at the edges or within the quasi-periodic ...
  • Quantifying Hidden Order Out of Equilibrium 

    Chaikin, Paul (Georgia Institute of Technology, 2018-04-20)
    While the equilibrium properties, states, and phase transitions of interacting systems are well described by statistical mechanics, the lack of suitable state parameters has hindered the understanding of non-equilibrium ...
  • Highly Efficient Oil-Water Separation Using Surface-Programmable Membranes 

    Zeng, Minxiang (Glenn); Zhang, Eric; Huang, Dali; Cheng, Zhengdong (Georgia Institute of Technology, 2018-04-20)
    The challenge of separating emulsified oil from oil/water mixture has sparked enormous research interests in developing advanced membrane technology. One of the most crucial elements to achieve high separating efficiency ...
  • Local and Global Avalanches in Sheared Granular Materials 

    Zadeh, Aghil Abed; Barés, Jonathan; Behringer, Robert (Georgia Institute of Technology, 2018-04-20)
    We perform a stick-slip experiment to characterize avalanches for granular materials. In our experiment, a constant speed stage pulls a slider which rests on a vertical bed of circular photoelastic particles in a 2D system. ...
  • Soft, Responsive and Semiconducting Gels 

    Rosu, Cornelia; Russo, Paul S.; Reichmanis, Elsa (Georgia Institute of Technology, 2018-04-20)
    Interaction of biopolymers with organic electronic materials provides an appealing opportunity to design electroactive materials for use in many applications especially bioelectronics. Because of their biocompatibility, ...
  • Exploiting Disorder 

    Nagel, Sidney (Georgia Institute of Technology, 2018-04-20)
    We are taught to understand solids by considering ideal crystals. This approach becomes untenable as the amount of disorder increases; for a glass with no well-defined long-range order, a crystal is an abysmal starting ...
  • Ordered and Disordered Motion in Dense Active Materials 

    Berthier, Ludovic (Georgia Institute of Technology, 2018-04-19)
    We discuss how the non-equilibrium driving forces introduced by the natural biological activity or by physical self-propulsion mechanisms generically affect the structure, dynamics and phase behavior of dense active media. ...
  • Symmetry Breaking During the Synthesis of Nanoparticles 

    Xia, Younan (Georgia Institute of Technology, 2018-04-19)
    Symmetry breaking is a ubiquitous phenomenon that occurs spontaneously when a system is subjected to variations in size and/or perturbations in terms of thermodynamic parameters. As a stochastic process, even small ...
