Query: Recent progress towards chemically-specific coarse-grained simulation
  models with consistent dynamical properties   Coarse-grained (CG) models can provide computationally efficient and
conceptually simple characterizations of soft matter systems. While generic
models probe the underlying physics governing an entire family of free-energy
landscapes, bottom-up CG models are systematically constructed from a
higher-resolution model to retain a high level of chemical specificity. The
removal of degrees of freedom from the system modifies the relationship between
the relative time scales of distinct dynamical processes through both a loss of
friction and a "smoothing" of the free-energy landscape. While these effects
typically result in faster dynamics, decreasing the computational expense of
the model, they also obscure the connection to the true dynamics of the system.
The lack of consistent dynamics is a serious limitation for CG models, which
not only prevents quantitatively accurate predictions of dynamical observables
but can also lead to qualitatively incorrect descriptions of the characteristic
dynamical processes. With many methods available for optimizing the structural
and thermodynamic properties of chemically-specific CG models, recent years
have seen a stark increase in investigations addressing the accurate
description of dynamical properties generated from CG simulations. In this
review, we present an overview of these efforts, ranging from bottom-up
parametrizations of generalized Langevin equations to refinements of the CG
force field based on a Markov state modeling framework. We aim to make
connections between seemingly disparate approaches, while laying out some of
the major challenges as well as potential directions for future efforts.
