We introduce a new micro-macro Markov chain Monte Carlo method (mM-MCMC) to sample invariant distributions of molecular dynamics systems that exhibit a time-scale separation between the microscopic (fast) dynamics, and the macroscopic (slow) dynamics of some low-dimensional set of reaction coordinates. The algorithm enhances exploration of the state space in the presence of metastability by allowing larger proposal moves at the macroscopic level, on which a conditional accept-reject procedure…

Efficiency and Parameter Selection of a micro-macro Markov chain Monte Carlo method for molecular dynamics

We recently introduced a mM-MCMC scheme that is able to accelerate the sampling of Gibbs distributions when there is a time-scale separation between the complete molecular dynamics and the slow

Multilevel Gibbs Sampling for Bayesian Regression

A multilevel Gibbs sampler for Bayesian regression of linear mixed models and the use of correlated samples is investigated for variance reduction to improve the convergence of the Markov Chain.

Coupled Coarse Graining and Markov Chain Monte Carlo for Lattice Systems

An efficient Markov Chain Monte Carlo method for sampling equilibrium distributions for stochastic lattice models and has comparable mixing properties with the classical microscopic Metropolis algorithm controlled by the level of coarsening and reconstruction procedure.

Adaptive resolution molecular-dynamics simulation: changing the degrees of freedom on the fly.

This work presents a new adaptive resolution technique for efficient particle-based multiscale molecular-dynamics simulations that allows an on-the-fly interchange between a given molecule's atomic and coarse-grained levels of description, enabling them to reach large length and time scales while spatially retaining atomistic details of the system.

Grand-canonical-like molecular-dynamics simulations by using an adaptive-resolution technique

This work provides a detailed theoretical analysis, supported by numerical tests, of the reliability of the adaptive resolution simulation (AdResS) technique in sampling the Grand Canonical ensemble and compares its method to the Insertion Particle Method (IMP) in its most efficient computational implementation.

Preconditioning Markov Chain Monte Carlo Simulations Using Coarse-Scale Models

The purpose of preconditioning is to reduce the fine-scale computational cost and increase the acceptance rate in the MCMC sampling by generating Markov chains based on two-stage computations by incorporating the coarse-scale information of the problem.

Partial differential equations and stochastic methods in molecular dynamics*

This review describes how techniques from the analysis of partial differential equations can be used to devise good algorithms and to quantify their efficiency and accuracy.

Overcoming free energy barriers using unconstrained molecular dynamics simulations.

Association of unconstrained molecular dynamics and the formalisms of thermodynamic integration and average force and the illustrative examples of the reversible unfolding of deca-L-alanine, the association of acetate and guanidinium ions in water, and its transfer across the water liquid-vapor interface are examined to probe the efficiency of the method.

Effective dynamics using conditional expectations

The question of coarse-graining is ubiquitous in molecular dynamics. In this paper, we are interested in deriving effective properties for the dynamics of a coarse-grained variable ξ(x), where x

A mathematical formalization of the parallel replica dynamics

By drawing connections with the theory of Markov processes and, in particular, exploiting the notion of quasi-stationary distribution, this work provides a mathematical setting appropriate for assessing theoretically the performance of the approach, and possibly improving it.

Introduction to the Kinetic Monte Carlo Method

The purpose of this chapter is to provide an introduction to this KMC method, by taking the reader through the basic concepts underpinning KMC and how it is typically implemented, assuming no prior knowledge of these kinds of simulations.
