AtC Methods for Dynamic Simulation of Solids
Weinan E (Princeton) and Xiantao Li (Penn State)

There are two main issues that we have to address in formulating general AtC methods that can model accurately dynamic problems with thermal effects:

1. The boundary conditions, or generally, constraints, for MD or other atomistic models.
2. The time scale problem.
   In this talk, we will present a systematic discussion of these two issues. We will give an overview of what has been done, and discuss some of the main misconceptions, and what the main obstacles are in order to design and implement successful AtC methods.
