Biosketch: Dr. David Ballantyne obtained his Ph.D. in 2002 from the University of Cambridge, and has been an Assistant Professor at the
Center for Relativistic Astrophysics in the School of Physics since 2008.  His research concentrates on topics in high-energy astrophysics
with an emphasis on interpreting existing data and making predictions for future observations. His main interests are the evolution of
galaxies and their central supermassive black...

Extreme-mass-ratio binaries, composed of a small compact object (SCO) and supermassive black hole (SMBH), are eventual observational candidates for future space-based gravitational wave observatories.  Theoretically, these binaries are examples of the as-yet not thoroughly solved two-body problem in general relativity.  Extreme-mass-ratio inspiral (EMRI) calculations proceed by using black hole perturbation theory.  The gravitational field of the small mass affects its own orbit in the background geometry,...

Sebastian Thrun recently left Stanford University and started Udacity. Udacity is an online university that seeks to reach the 99% of the world population that are presently excluded from high-quality higher education. The first class on Artificial Intelligence, jointly offered with Stanford, attracted 160,000 students, of which 23,000 graduated with Stanford-level qualifications. The speaker will discuss his experience with traditional forms of education, and brainstorm how higher education may look like in the digital age.

Thrun is co-founder of Udacity, a Google VP, and a Stanford Research Professor. At Google, he runs Google X, home to the Google self-driving car...

In this talk we will focus on the elasticity of soft filamentous networks. We will begin with the mechanical behavior of fibrin networks which
have been shown to be highly extensible in recent experiments. We believe that the high extensibility of the networks has its origins in the force induced
structural change in the proteins making up the fibrin fibers. We will present a model and experimental evidence in support of our hypothesis. In the
remainder of the talk we will describe how the quasi-harmonic approximation of statistical mechanics can be combined with the finite element method (used
in structural analysis of buildings,...

Understanding the new states at the interfaces and the resulting whole behavior of the heterostructures and multilayers is a hot topic at the forefront of the fundamental research, as demonstrated by the huge number of theoretical and experimental studies published in the topmost level scientific journals. In this context, s...

Joseph Ford saw beauty in "Chaos" and the potential for ``villainous chaos" to be used in a constructive manner. His ideas have proved prescient. The talk will focus mainly on how chaotic dynamics may have played a key constructive -- rather than destructive -- role in shaping certain features of the Kuiper belt: in particular, the formation and properties of binary objects in the transneptunian part of the Solar System. Kuiper belt binaries stand out from other known binary objects in having a...

Bulk Topological Insulators are a new phase of electronic matter which realizes a non-quantum-Hall-like topological state in the bulk matter and unlike the quantum Hall liquids can be turned into superconductors. In this Lecture, I will first review the basic theory of topological matter and...

I describe a unified approach to locating key material transport barriers in unsteady flows induced by two-dimensional, non-autonomous dynamical systems. Seeking transport barriers as minimally stretching material lines, one obtains that such barriers must be shadowed by minimal geodesics under the metric induced by the Cauchy-Green strain tensor field associated with the flow map. As a result, snapshots of transport barriers can be explicitly computed as trajectories of ordinary differential equations. Using this approach, hyperbolic barriers (generalized stable and unstable manifolds), elliptic barriers (generalized KAM curves) and parabolic barriers (...

A neutrino detector, capable of detecting the neutrinos from the Sun’s fusion cycle, was strongly requested by the Theorists working on the Solar Model in the early 1960’s.  The Cl37 → Ar37 detector scheme used by Davis and Harmer at the Savannah River Experiment in the 1950’s was suggested as the basis for a scaled up Solar Neutrino Detector. The details of the design and engineering of this scale up from “Laboratory” to “Production” one mile underground at the Homestake Gold Mine in...

Topological insulators, a novel kind of three-dimensional insulators can have a bulk insulating gap but non-trivial topological surface states. The surface states of these topological insulators show Dirac-like behavior with the spin polarization locked perpendicular to the electron momentum by the effect of strong spin-orbit interaction. As the locking protects the surface electrons from back scattering, they are predicted to have high mobilities. The surface state of Bi2Se3 and Bi2Te3 topological insulators has been observed by angle-resolved...
