Etienne Ghys: "Chirality in Dynamics"
Abstract: Consider a dynamical system in 3-space, induced by some vector
field. Its trajectories, the phase portrait, may present some asymmetry
with respect to a mirror image.
I would like to discuss some examples of such "chiral vector fields".
I'll introduce a family of "fully chiral" dynamics and explain some
consequences on the topology of periodic orbits.
F. Duncan M. Haldane, "Topological insulators"
Abstract: TBA
Moty Heiblum: "Entangled Electrons in the Solid State:  Quantum
Interference and Dephasing"
Abstract: I will describe two connected experiments, where pairs of
electrons were entangled in a solid state Mach-Zehnder Interferometer
(MZI), leading to entirely different outcomes. In one experiment electrons
in a 'which path' detector were entangled with electrons in a MZI,
leading to total dephasing of the interference.  Under these conditions,
the interference that was lost had been recovered by doing a 'post
selection' type measurement (via cross-correlating currents); proving that
the phase information stayed in the system. In another experiment, making
use of two MZIs (in a novel 'two particle interferometer'), two
remote, indistinguishable, electrons were entangled only due to their
exchange statistics, namely, without ever interacting with each other (in
a similar fashion to the Hanbury Brown - Twist photonic experiment).
Though each electron's paths did not enclose a flux, cross correlating the
current fluctuations in the two separate detectors revealed Aharonov-Bohm
flux dependent oscillations.
Subir Sachdev: "Quantum criticality and gauge-gravity duality"
Abstract: Quantum critical points (or phases) are special locations in
parameter space where the ground state wavefunction has long-range
and scale-invariant quantum entanglement between the local
degrees of freedom. Such points are also the key to explaining
a wide variety of experiments on many modern electronic materials.
In recent years, ideas from string theory on the duality between
quantum gauge and gravity theories have provided a new physical
on quantum criticality. I will give an overview of these developments
and their future prospects.
Cedric Villani: "Landau damping, or relaxation without entropy production:
the limits of Boltzmann's paradigm"
Abstract: Boltzmann's statistical entropy, the notion  of macroscopic
irreversibility and molecular chaos, and the Boltzmann equation were at
the basis of a little conceptual revolution at the end of the nineteenth
century. In 1946, Landau shocked the scientific community by finding
irreversibility where there did not seem to be. This ended the reign of
entropy as the dominant explanation for irreversible behavior. It took
another 2/3 of a century before Landau's contribution was fully justified,
and, unexpectedly, related to some of the other most famous paradoxes of
classical mechanics. The present talk will explain in simple terms these
conceptual revolutions. It will be complementary to the preceding talk at
the Weizmann Institute, and independent of it.
