Harvard UniversityOrganizer Department of Chemical and Biological PhysicsContact Abstract Show full text abstract about Realizing and engineering optical non-linearity at the level...» Realizing and engineering optical non-linearity at the level of single photons is a goal of scientific and technological significance. We obtain strong interaction between propagating photons by coherently coupling them to Rydberg atoms in a cold gas. While slowly traversing the medium, the "Rydberg polaritons” interact via the Van-der-Waals force, owing to their large electric dipole-moment. We are able to vary the dynamics of the
two-photon wavefunction from dispersive (Schrodinger-like) to dissipative (diffusion-like) and observe strong bunching, anti-bunching, and a conditional phase-shifts of 1 radian for two individual photons.

Predicting deliberate decisions and the onset of conscious intention

Div. of Biology, California Institute of Technology, Pasadena, CAOrganizer Department of Brain SciencesContact Abstract Show full text abstract about Human behavior was shown to be predictable from neural activ...» Human behavior was shown to be predictable from neural activity before subjects reported having decided on the contents or onset of their actions. This was suggested to challenges the role of consciousness intentions in decision making, and through it have far reaching implications for the notions of free will and moral responsibility. However, these studies focused on non-ecological, arbitrary decisions – like raising the left or right hand for no reason or purpose and with no consequences – which are not typically held to be the hallmarks of freedom, not to mention assigning blame or praise. We wanted to understand to what degree this ability generalizes to deliberate actions, so we analyzed intracranial, human brain activity in a competitive environment – a matching-pennies game. We were increasingly better able to predict such actions with time before movement onset, retrospectively and even online and in real time. We further discovered specific neural differences between deliberate and arbitrary decision making using EEG. And we also found bias activity in monkey DLPFC and striatum that may help explain the early predictions in arbitrary decisions. I will sketch some features of a model of action selection that is congruent with the above findings. -

Increment distributions which is applicable to a wide range of turbulent
systems. In order to get insight into the role played by the dissipative structures
we compare different turbulent systems e.g. 2D and 3D Navier-Stokes flows, 3D
MHD flows.
In addition I will present results on conditional Lagrangian statistics where we
propose a novel condition for Lagrangian increments which is shown to reduce
the flatness of the corresponding PDFs substantially and thus intermittency in
the inertial range of scales. The conditioned PDF corresponding to the smallest
increment considered is reasonably well described by the K41-prediction of the
PDF of acceleration

We present an attempt to classify different dynamic processes in biological macromolecules on the ns-ps time scale. It is based on analysis of quasileastic neutron scattering (QENS) data, dielectric relaxation spectroscopy and MD-simulations studies of dynamics of proteins, RNA and DNA. We identify four relaxation processes in dynamics of biomolecules on the picoseconds-nanosecond time scale: (i) fast picosecond relaxation that is strongly coupled to the solvent dynamics and is traditionally ascribed to a caged motion of residues; (ii) methyl groups dynamics that seems to play an important role in proteins; (iii) “localized diffusion” that seems to be strongly coupled to dynamics of hydration water; (iv) larger scale relaxation process in the ns-time scale that we ascribed to motions of domains or secondary structures. The microscopic nature of these processes and their dependence on hydration water are discussed. We propose a general picture of biomolecular dynamics on the ps-ns time scale. At the end we emphasize the difference in dynamics between proteins and nucleic acids and address the question of their evolutionary evolvements.
