Simons Meeting on

High-Dimensional Dynamics

New York City (NY)

April 11-12-13, 2018

Understanding dynamics in very high dimensions has become a central problem in many different fields.

The aim of this meeting is to bring together theorists working in biology, machine learning and physics

to discuss the main questions and present recent progress done on this topic in these different fields.


The workshop is sponsored by the Simons collaboration Cracking the Glass Problem.


Organisers: M. Baity-Jesi, G. Biroli, D.R. Reichman

Keynote Speakers

B. Altshuler (Columbia), Between Localization and Ergodicity in Quantum Many-Body and Qubit Systems

J.-P. Bouchaud (Capital Fund Management), Network models for economic crises

L. Bottou (Facebook Research and NYU), Convexity “à la carte”

D. Fisher (Stanford), Chaotic eco-evo dynamics in high dimensions

J. Kurchan (ENS Paris), Threshold dynamics and fluctuations

S. Sastry (Jawaharlal Nehru Centre for Advanced Scientific Research), The energy landscape view of dynamics in glass forming liquids and glasses

A. Jagannath (Harvard), Convergence to equilibrium for mean field spin glasses

M. Tarzia (Université Pierre et Marie Curie), The Anderson model on the Bethe lattice: non-ergodicity and glassy dynamics


The workshop will consist in long 1-hour talks by key-speakers listed below and shorter presentations (25 mins+5 mins of questions) by collaborators and affiliates of "Cracking the Glass Problem", working on high-dimensional dynamics. The aim of this session is to foster interactions within and outside the collaboration. The event will finish on Friday April 13th around lunch time, in order to allow for discussions in the afternoon.
