PROGRAM

Understanding rare events is crucial in modeling how complex many body systems organize, leading to diverse phenomena such as crystal nucleation and growth, chemical reactions in solution, self-assembly of macromolecules, protein folding and dynamics of disordered systems. Related phenomena occur in quantum field theory and cosmological phase transitions that may set the large-scale structure of the universe. Unifying theoretical concepts in this area require effective coarse-grained descriptions and non-equilibrium statistical mechanical methodologies. This program will bring together key people working in this area aiming at the development of new theoretical concepts and computational tools.

PAST EVENTS IN THIS SERIES

Rare Events in Biology
February 3-4, 2010

Most of life gets spent waiting for something interesting to happen. Cancers arise only once a particular combination of chance mutations enable a cell to divide unchecked and start invading neighboring tissues. A protein may spend much of its time on its way to being folded dwelling in unfolded or misfolded conformations until the right fluctuation jolts it into its native shape. And whether in the test tube or out in the wild, it is often a sudden event, such as the introduction of a toxic drug, or a dramatic change in climate, that confers selective advantages on particular members of genetically diverse populations of organisms. The common thread among all these stories is the importance of rare events to the dynamics of biological systems. The purpose of this symposium is to examine the impact of rare events on biology from both theoretical and experimental perspectives, at length scales ranging from single molecules to whole species, and in a variety of contexts including the clinical and the ecological.

Complex energy landscapes and long time dynamics
12-13 November 2009

Nucleation phenomena in materials, relaxation processes in glasses, and large-scale conformational changes in macromolecules involve collective motions of many particles that occur rarely on the time scale of the atomic dynamics. Understanding and predicting these processes poses great theoretical challenges. This workshop intends to provide an overview of the field and stimulate the discussion on the guiding principles that govern this large class of phenomena.

Confirmed speakers include:Christoph Dellago(University of Vienna),
Weinan E (Princeton), Hannes Jonsson (University of Iceland and Brown University), Randall Kamien (UPenn), Yannis Kevrekidis (Princeton), David P. Landau (University of Georgia), Michele Parrinello* (ETHZ-Lugano Center), Bernhard Trout (MIT), Haw Yang (Princeton) and Stefano Piana-Agostinetti (DE Shaw)

*M. Parinello will give Joint Physics/PCTS Colloquium on Thursday, Nov. 12, 2009 at 4:30 pm in Jadwin A-10
