Inhomogeneous multiscale dynamics in harmonic lattices
(American Institute of Physics, 2005)
We use projection operators to address the coarse-grained multiscale problem in harmonic systems. Stochastic equations of motion for the coarse-grained variables with an inhomogeneous level of coarse graining in both time ...

Formal derivation of dissipative particle dynamics from first principles
(American Physical Society, 2005)
We show that the Markovian approximation assumed in current particle-based coarse-grained techniques, like dissipative particle dynamics, is unreliable in situations in which sound plays an important role. As an example ...
