Data Challenge

This page is a complement to our challenge’s page at https://challengedata2.ens.fr

Relating structure to long-time dynamics in supercooled liquids is a long-standing problem. Several ideas have been put forward and tested in the physics literature. The idea of the challenge is to address this problem from a different angle, using a data-driven approach.
The use of the ML approach for glasses was introduced by the team of Andrea J. Liu, in particular in collaboration with Ekin Dogus Cubuk and Samuel S. Schoenholz. See refs. below.

Here is our python code to handle Periodic Boundary conditions (with comments), which is also included in the input data .zip file.

The general review on glasses we mentioned in the slides is cited below. If you have trouble getting it (or others), please ask us (also, there is sci-hub).
