Abstract: Abstract The simulation of multiscale problems remains a challenge in many problems due to the complex interaction between the resolved and unresolved scales. This work develops a coarse-grained modeling approach for Galerkin discretizations by combining… read more here.

Abstract: Coarse grained (CG) molecular dynamics simulations are widely used to accelerate atomistic simulations but generally lack a formalism to preserve the dynamics of the system. For spherical particles, the Mori-Zwanzig approach, while computationally complex, has… read more here.

Abstract: A new derivation of the generalized Langevin equation (GLE) of motion is presented that exactly describes the reduced dynamics of a particle system acted upon by a time-dependent force field with a generalized (velocity-dependent) potential… read more here.
