Scale Interactions in the Ocean Circulation: Two Observational Process Studies
More information Time 11:00 - 11:00Location Sussman Family Building for Environmental SciencesLecturer Dr. Stephanie Waterman
The University of New South Wales and the ARC Centre of Excellence for Climate System ScienceOrganizer Department of Earth and Planetary SciencesContact Abstract Show full text abstract about In this talk I will introduce my research on scale interacti...» In this talk I will introduce my research on scale interactions in oceanic processes and the implications of these interactions on the large-scale circulation.
I will discuss the nature and importance of scale interactions in the physics of the ocean and the ocean's role in the climate system, and why our understanding of these interactions is critical to our ability to model the ocean in climate models, interpret our observations and simulations of the oceanic circulation, and design effective observing systems.
I will then describe two examples from my current research that aim to further our
understanding of specific ocean processes in which scale interactions are key: 1. a study of eddy-mean flow interactions in oceanic western boundary current systems such as the Gulf Stream and Kuroshio Extensions, and 2. work on wave-mean flow-turbulence interactions in a Southern Ocean mixing hotspot. Each considers different interacting scales and examines different processes which in turn have different impacts on the larger-scale circulation. They share however a common aim, to understand the physical mechanisms underpinning the observed system behaviour, as well as a common approach, uniting process-targeted observations and idealised process modelling.

Noncovalent synthesis in aqueous medium: diversity and pathway-dependent self-assembly.
More information Time 10:00 - 10:00Title Organic Chemistry - Students seminarLocation Helen and Milton A. Kimmelman BuildingLecturer Yaron Tidhar
Ph.D. student under the supervision of Dr. Boris RybtchinskiOrganizer Department of Molecular Chemistry and Materials ScienceContact Abstract Show full text abstract about Most molecular self-assembly strategies involve equilibrium ...» Most molecular self-assembly strategies involve equilibrium systems. Yet, strong noncovalent interactions may result in nonequilibrium self-assembly, where structural diversity is achieved by forming several kinetic products based on a single covalent building block. I demonstrate that well-defined amphiphilic molecular systems based on perylene diimide/peptide conjugates exhibit kinetically controlled self-assembly in aqueous medium, enabling pathway-dependent assembly sequences, in which different organic nanostructures are evolved in a stepwise manner. In order to better understand the processes leading to the ordered self-assembly of aromatic amphiphiles in water, a kinetic mechanistic study was performed. In this study, aqueous self-assembly of chiral perylene diimide (PDI) amphiphile into highly ordered crystalline arrays was investigated using UV-vis and circular dichroism (CD) spectroscopy coupled with cryogenic transmission electron microscopy (cryo-TEM). The latter provides direct structural imaging of self-assembly progress. Molecular dynamics calculations were performed as well. We observed a three-step mechanism: 1) nucleation; 2) growth; 3) coarsening. The nucleation-growth process fits a modified Kolmogorov /Johnson/Mehl/Avrami (KJMA) model. We observed that the initial state of the system is an amorphous aggregate that gradually transforms into a highly ordered system. Activation parameters suggest that de-solvation plays a significant role in the process.
Photophysical measurements of a set of materials similar to the ones studied in the kinetic part revealed excellent exciton mobility in ordered PDI arrays. The relation between structure and function was demonstrated using a set of kinetically formed structures that allow tuning of the exciton mobility via morphology of the self-assembled structures.

Several results will be presented concerning the dynamics of poker tournaments (and in particular, the wealth distribution or the properties of the richest player), the universal behavior of the total number of leaders in a general competition (including poker), sport championships and the relation between final rank and fraction of wins or the distribution of victory streaks, and the "minimax thermodynamics" of tree games (like chess) and its link with a model of random polymer.

Exact Solutions of Pairing Hamiltonians
More information Time 14:45 - 15:45Location Edna and K.B. Weissman Building of Physical SciencesLecturer S. Pittel
University of DelawareOrganizer Department of Particle Physics and AstrophysicsContact Abstract Show full text abstract about The exact solution of the BCS pairing Hamiltonian was found ...» The exact solution of the BCS pairing Hamiltonian was found by Richardson in 1963. While little attention was paid to his solution for the remainder of the century, there began in the early 2000s a flurry of activity that focused on its applications in different areas of quantum physics. In this talk, following a brief historical overview of pairing in quantum systems, I will review Richardson's solution and its generalization to the wider class of Richardson-Gaudin integrable models and then discuss applications of these various models to problems of contemporary importance in nuclear physics.
